    The best HL1 sp-mod along with Timeline 2 & 3.

    The author’s name is Koumei Satou – he’s Japanese and made Peaces Like Us (HL) and Mistake of Pythagoras (HL2 – the best single-player HL2 mod).

  3. when I try to get a game running it says Invalid DLL Version!!!

    A must play with (as usual) with cool scenes.

    Like the HL story? this is your mod.

  5. just getting in to the mod but did have some loading troubles. I had to start it in software and not open gl, then after loading in both patches it cleared up. I also have the hd pack in I believe hf v 1.1.1. or someting and went back to open gl and it took the better graphics. I dont know why before it would only show the first part then go to a black screen but you could move gorden. I emailed the developer and pointed out the tidbits. so far is it really good.

    Rating: 5/5
    Good: Great length; lots of new content; scripted scenes are movie-like.
    Bad: Old textures.

    I first heard about Sweet Half-Life from an email, and I have to admit, I thought it was a kinda cheesy name. It doesn’t give any clues as to what the plot is of the mod, nor does it sound mysterious or anything, or instill a sense of awe in the player. But I decided to give it a go (after waiting in line forever at Fileplanet), and I am very glad I did. This is easily one of the best mods based off of the stock Half-Life textures and content by far.

    Quick overview: You are a Black Mesa employee who also happens to be named Gordon, though Freeman is not your surname, and you do not posses a degree in Theoretical Physics from M.I.T. Instead, you are a mid-level manager appointed to a storage section of Black Mesa. Sweet Half-Life takes place over the same time period as Half-Life 1, in case you were wondering.

    Okay, where to begin? I’ll start with the content. There are new models in the form of friends and enemies, from this world and the next. You finally have some scientist buddies in HEV suits to help you in Xen against the Gargs! There are new weapons for you to use, and they look great. The arms look great, nothing out of proportion, animations are fine, and the new weapons use their own ammo (except for MP5 grenades – they are shared).

    Next, we have the sheer size and length of Sweet Half-Life. It is nearly a third as long as Half-Life 1, and all of the maps are LARGE. You won’t see the ‘loading” screen very much, its great. All of the levels are well laid out, the architecture is impressive, and textures line up accordingly and accurately. Moving on, are the scripted scenes. Wow. These are very, very good. Valve themselves would have a tough time doing better.

    I hate to make the review short, but I can’t devote a whole paragraph to something that doesn’t exist. If you want me to really find something that I didn’t like, it would be that there weren’t many new textures. There were some, but not as many compared to Poke646 or They Hunger. That’s about it.

    Compatibility: Sweet Half-Life was built for the non-Steam version of Half-Life, meaning most of its content is contained in a .pak file. So if you have the non-Steam version of Half-Life, then you should be fine. However, I’m not one to play on outdated technology! So I did a little experiment. Using GCFScape, I was able to unpack everything from the .pak file into their correct folders in the \half-life\ folder in my Steam directory, and everything played fine. So, those with Steam are still able to play Sweet Half-Life!

    Summing up, this mod rocks, and I whole-heartedly recommend it to everyone.

  7. would like to play this one but, after the intro, my screen goes black. I can hear myself move around, but can’t see thing.

    Is the vvideo setup for open GL ? Are you using the steam version or original?

  9. Original. I’ve tried it in Open GL, Direct 3D, & plain software mode. That was the first thing I tried but, still the same thing. I thought I had played this one some time ago but, I don’t think I have.

  10. Ah, in the readme file, it says not to play if you have the HD pack. I had read somewhere at some time that you could modify this without uninstalling everything. Is this correct & if so, how do you do that?

  11. goodness goddess alyria. just a few posts up or being a goddess look down. hehe. I had the same problem. load the patches from the authers site. it will work, I can give ya a hint ole mighty one. it is a great hard mod. I am stopped on the what I believe to be the final battle. it says I cant win, but I refuse to surrender. hehe. post if you have any more problems and me just a mear mortal will attempt to help thee.

  12. p.s. after loading in the patches use open gl.

  13. I went to the sites last night. An English version which had no d/l links listed ( and the Japenese site but, even being a Goddess, I can’t read Japanese. I’ll see if I can find the patches somewhere else. I didn’t even see that post above so thanks!

  14. i would think a goddess would be able to read any language. but then the simple minds of we mear mortals. I am stuck downloading the newest patch for the offical army game but will do what I can to see if I can give a a good link. stay tuned it might not take that long. I think I have it in my favorites.
    and in another note, do you like anami? the author has put some in the mod. very neat. also this guy also made the half life 2 mod mistake of phythagorious, a outstanding mod. will update ya…

    all patches are on his english site available here.


  16. Just disregard my above comments. Found the english version of the site with the patches. I just like to play the games, not get too overly technical about it. After installing the patches, it still does the same thing. Does it have to do with the HD pack (which I have)? How do I correct that problem?

  17. ole mighty goddess alyria. I fear your powers are not that strong if thou cant read the japenese. but, fear not for I have the links. links in english, my fair lady. hehe.

    look at the download part and get all the patchs. my copy a sierra haflife .1.1ect..has worked fine with hd pack on all the mods I have played. I gave up on steam hl1 a wile ago

    note to phillip, maybe include the link above to this posting site. for phillip is the one true god. I bash aliens and make meny a sacrifice in his name. good luck let me know what happens.
    ps. I might not be able to ge to you till saterday night if this doesnt help.

    Uninstall it.Or use it with steam.Mine works fine in steam.

  19. Er, I posted this question earlier on “Ask a question”. How do you install hl to run in steam? I bet this is why I never see any girls posting around here. Bet you guys hate it. Oh well, I’ll check back later to see if anyone helps further. Now, I have to go bake cookies & stuff for my nieces/nephews.

    Install steam.It will then search your pc for any other compatible games and install them for you.Then it will ask you to enter your key.If,like me you had a stand alone half life disk it will will also give you opposing force and blue shift.If it does not ask for a key you can activate it by clicking the games tab in the toolbar.

    EDIT:I like cookies too.Peanut butter is my favorite (wink wink)

  21. Well, I already have steam installed. For some reason, HL 1 isn’t in my list of games. I guess I’ll just have to uninstall Steam & go through the whole process again. Sure is a lot of trouble to play just one game.

    Hey andyb … my favorite is the peanut butter too. I’ll think about you while baking them. I bet you like peanut butter fudge too?

  22. andyb 934 comments

    22nd December 2006

    Fudge?Yummy! If you have steam installed click the games tab in the toolbar and select “activate a game”

  23. alyria, I went to planet half life to get you the link to the upgrade for hl 1 to the final version which is what steam uses.
    they changed their file layout I couldnt find it quick. but I suggest trying that.
    good luck…

  24. Too late. Oh well, to be continued …

  25. Oh yeah andy … btw, if this doesn’t work … suffice to say your ass is mine!

    Hehe.Sounds fun!!

  27. Something really told me you’d say that.

    Okay, I uninstalled Steam, re-installed it & Half Life 1 is not listed anywhere. Now what Mr. Smarty?

    As I said above,select the games tab (beside store tab) and select activate a game.

    Edit: I had a custom GUI so I reverted back to default.The toolbar goes File, View, GAMES, Help – select Games

  29. There’s nothing there to select except my HL2 games. If I click on Activate a Product & put in the key for HL 1, it tells me it’s already activated. Just never mind. Thanks andyb & john for all your help. Happy Holidays to all!

  30. Finally! I finally uninstalled my HL & re-installed it without the HD pack. Mine came as the platinum collection, so I did it as a stand alone. Works perfectly fine now. Although, I SWEAR, I read somewhere that there is a way to disable the High Definition by renaming a file. I wish I could remember where I saw that at.

  31. we mortals rejoyce as goddess alyria now begins to save us in the world of sweet half life.
    sorry to hear about all the trouble you had. great mod.

  32. Thanks John.

  33. Okay, I was getting really discouraged during the first part of game play. Some of these mods become monotonous to me if they don’t present some real change. I love to be intrigued & I know most of you guys love being in Black Mesa. I, however, love being taken out of that element every once in a while. So, I was humdrumming along until it got to the “twist” (so to speak). Everything changed after that. What a remarkable game! It quite simply took my breath away. Those bad ass aliens were awesome & tough little buggers but I loved the spaceship. The music also set the right feel for it. I could go on & on about the great technical quality of the mod, but most of you guys already know that. Definitely (as suggested) one of the BEST hl mods to play. I plan on playing through it again as soon as I finish Black Ops.

    A good mod this with some groovy Sci-fi references, Brazil and 2001 to name the easy ones. Nice branching story and “impenetrable” B-movie plot. Really good maps and set peices. BTW use Explorer or look in either HalfLife of Valve folders for Pak1.pak, rename it to say PakOff.pak and you have disabled the HD content.

    Ok, since you all seem to be such experts on this mod, perhaps you can help me with a rather nasty problem I have with it.

    I install the game into my Steam version of Half-Life, load it up and start playing. All initially seems fine, however when I try to shoot any living creature with the pistol (I’ve experienced this with the headcrab and the “zapper” alien), the game crashes on me. I can fire the pistol as per normal, but if I hit a creature, then I get dumped back to the desktop.

    I’ve tried using every patch from the website, but to no avail. I’m even using the original models, but the problem still occurs. Any ideas?

  38. Where or what do I do after turning on the reactor and killing the 2 gren monsters?If you jump in you just float around

  39. All set figured it out thanks

  40. What do I do at the part with the spinning pipe?

  41. Find a went in the roof somewhere

  42. i run this game, but first level don`t run, it is black screen, please help!

  44. Make sure you don’t have the High Def pack installed.

  45. Hi!

    I have Half-Life 1 and I installed High-Def Pack. Black Screen is in first mission, after intro…

  48. Play It Now!

    THANKS IT` WORK I finished this mod and I think is really good!

  49. Think Twice

    This mod is HUGELY flawed, I was at it for a couple of hours and ran into at least four sequences of play where if things don’t happen in a certain, obscure order, you can’t progress through the game.

    I’ll describe one example. At one point a marine is fleeing an alien. Both are coming toward you. You, of course, shoot the marine before he can kill you. The problem is, if you do that, the alien then doesn’t perform an unlikely action that allows you to proceed through the mod. There’s no reason for you to think the marine has to live (only to be killed by the alien) for the mod to continue. So you wind up running around for 15 minutes trying to figure out how to get to the next section.

    As I noted, this happens way too often. Also, the AI is poor by HL standards. Several times enemies stand around waiting to be shot; even the sniper babes will wait to be taken down.

    I appreciate the effort the designers put into this–they obviously worked hard. It’s too bad (as with so many mods) they didn’t do just a little more testing and tweaking.

  51. This is so cool and in this mod you have scientist with HEV on them and they can carry a weapon the best part is that they can’t be killed so easy

    Without any doubt one of the ten best SP-Mods for any shooter I ever played.
    Some tricky parts,brains needed now and then. The mod must be played twice
    to play it all. It starts easy but it gets hard later.

    Definitely worth playing for the story and “different-ness” of it. I found it very puzzling and frustrating at times… and I’m actually still playing it.. Right now I’m stuck in the part with the tall pedestal and the ship that flies around blasting you with blue/red scanning lights. I’m sure I’ll figure it out eventually. The hints page is nice, but it would be cool to have a walkthrough, not all things are covered by the hints. e.g. the hints say to get the “long jump” thing, but what is it, how is it used, etc? If anyone has any hints for that red/blue blasting ship, I’m all ears.

  56. SuperFlyTNT

    31st July 2008

    OK, it wasn’t that hard… just shoot for the two engines… after this point, the game is essentially over… some really cool scripted sequences follow. Apparently there’s an alternate ending… in the hints page here: I didn’t see several of those, so I must have taken route B. Guess I’ll have to go back and figure out what route A was.

    Overall, a very good mod, worth playing for sure. I can’t believe it’s now 2008 and there are still good mods out there for HL1 that I haven’t played yet.

  57. This mod would be great, but it has a flaw in it. When one gets to the scientist that needs to be rescued, the one behind the table, he fails to follow or otherwise move from his spot. I found this particularly frustrating. If anyone has any ideas about how to remedy the situation. I’d be interested.

      You have the high definition models installed?If so, then the scientist is missing a jump over table animation, therefore making him stuck. The same thing happens with a marine earlier in the game, but since he’s killable it doesn’t matter.

    I take it you know the trick of reverting to an earlier savegame and thereby re-enter the level and hope to trigger the scientist that way? Other than that, can’t think of anything…

    boring and ugly. avoid liek the plauge.

  70. Play It Later

    I’m very dual minded on this mod. This is almost certainly a case where the author pushed their modding abilities to their very limit, there are numerous cases where scripted sequences might go bad and result in something that needed to happen to progress in the game not happening, but when the scripted sequences do work, they work brilliantly. This mod actually has a divergent path, so you’ll want to play the game twice (or at least one and a half times, if you leave a save point to backtrack to at the proper point. Hint: Gonarch)
    There are also places that have bad voice acting, at least one npc model that doesn’t fit the HL1 style AT ALL, and it doesn’t protect you from getting into areas that you can get trapped in at all, but I think the various amusing skits and classical sci fi references along the way make the game well worth putting up with the few minor niggling details.
    One point of note is that the beginning has a sequence where you have to protect a scientist from a Garg without any weapons at all, however the game doesn’t give you any hints at all that you need to protect the scientist except by possibly shutting down the game when he dies and saying “game over” (it doesn’t even give you a “failed to preserve mission critical personnel”) Knowing this in advance should help make that sequence far less frustrating.

    Keep a running list of backup saves so that you don’t have to start over completely if you end up with a futzed up scripted sequence. It’s heavily flawed, but also heavily epic when you managed to get around those flaws, and I’m not one to use the term “epic” lightly.

    Oh weell just as it’s name says, this mod is sweet is great, defenetly one of the best HL1 mods ever, also I played with the steam fix verssion which is available, on mod DB, and is highly recomended, I had no bugs at all, and is a really cool verssion, you only need to have the steam HL1, and forget about bugs, well only for little strandings in some elevators, but in spite of that this is a great mod, like those like they don’t do any more in this days, with altern paths and new weapons and ennemys, really koumei satou is a must play in the HL universe, the UFO robot at the end reminds me it’s mistake of pytagoras HL2 mod, also a good one!,

    This mod is really if you like everything over the top. Lots and lots of enemies at once, with plenty of ammo for the powerful weapons. However, in my opinion, just throwing 3 gargantuas at me at once does not make for a fun experience. The level design is poor and it is terribly unclear what you have to do at times. Also, the way things were presented, like the cutscenes, and the Half-life dialogue used when it didn’t really make any sense, just left me with a feeling of a really unprofessional and poorly done mod.

    Don’t get confused by the name of this mod, it’s really sweet – cause it was made with love, well-mapped and contains plenty amounts of action etc. etc.!


    -Long playtime
    -Amazing design and gameplay
    -Tons of action, guaranteed!
    -Pretty neat ideas (won’t tell now!)
    -Different ways after chooseable after some playtime (yes, means 2 different endings)
    -New weapons, sounds, enemies etc.
    -Very nice scripted sequences, surprising!


    -Some bugs (scripts, clipping, crashes)
    -Partly huge areas, a bit long walktime
    -Sometimes boring-looking levelpipes, not much detail
    -Minor performance issues (Xen) EDIT: okay, I accidently played in GL not D3D O:)

    The spaceship may not be the greatest design, but fighting the aliens was fun, especially with their own original weapon. Overall, this mod is enjoyable. The final fight is way too hard and that’s followed by the surreal bit which should tell you not to take it seriously.
    The only glitch I had was getting stuck on various lifts/platforms. I had to noclip to move off them.

  77. Ten Four Reviews

    7th August 2012

    Single Player First Person Shooter Maps and Mods for Half-Life 1, 2 and Episodes 1, 2 and 3

    I first played Sweet Half-Life soon after it first came out, coming up on a full year ago. I remember loving it. But what I forgot is how awesome the experience really was – it required my playing it all over again to remind me how fun SHL really is. I can only hope you can forgive me and Ten Four for taking so long to post a review.

    SHL comes to us from a small team, led by Marc Ellis and Koumei Satou, who is known for previous mapping efforts including the well-received Peaces Like Us for Half-Life. And KS’s style shows through in this pack – though not as blatantly weird as Pieces, SHL has some touches of offbeat design that keep it interesting.

    Just about everything is simply sharp in Sweet Half-Life. The level design, the puzzles, and the game flow are all first-rate. SHL has a couple of new enemies (including a pretty tough heavy grunt), new weapons in addition to the original HL weapons, and even friendly scientists in HEV suits that can kick some serious ass with the rocket launcher or the tau cannon.

    Continue reading the review on Ten Four…

    Buggy, but worth the time in the end. This is another old Half-Life mod I’ve been meaning to play for ages, and I finally got around to. The mapping is stellar, and there’s some clever modelling too- like the HEV scientists. It has some very neat scripted sequences and cut-scenes as well.

    However, on the other hand, this mod has some really annoying bugs. There were a few times doors that were supposed to open simply didn’t, and I was forced to use no-clip just to advance. Still, despite this, it really was an interesting mod with a lot of effort put into it. Don’t rush to download it, but if you have time, definitely play it.

  79. Please tell me at what point the action begins mods. I Freeman suits suit, doing an experiment and further events develop normal HL. When the story begins this mod?
