The HL Invasion story starts at the end of Half-Life. Remember, you were in a train with the strange G-man … Fortunately, scientists hidden in a subsidiary laboratory with Black Mesa manage to repatriate you there with a space probe, in which you jumped just before the G-man kills you.
Once awoken, you discover this secret laboratory that the government forces haven’t discovered yet. You are watching a teleportation experience, when suddenly overtrained marines invade this hiding place … From this moment, you’ll never be alone … This new trip will lead you into subsidiary areas with Black Mesa where you’ll get more revelations about the government objectives and the world of Xen …

Is it possible to do the part with the security cameras without the patch? If so…how?
7th September 2006
It is, as long as you keep in mind that you must not be detected by them.
I take it that the hint I gave last time was not sufficient, so here is another: the door is not the only possible exit from the lift… and you need to exit before the door opens.
10th September 2006
Please someone tell me how to get past the part after sewer pipe when you are stuck in the “square” path under the floor-(metal grates) and you can see up. the other fellow asked this question but figured it out before the answer was given..
(something about the ‘use’ key?, is this the right place , because i tried that) .
i dont know what i’m looking for…
thankx
11th September 2006

Aggggg!

This game continues to give me problems. The mapper is too creatvie and makes things very difficult. It’s so hard to find passwords.
Where I amd stuck on is a part where you have the tank. Its right after the part where you call in the helicopter and kill it. The door opens and you go through a passage into more battle. There are I think 2 jeeps, 2 parked tanks, lots of infantry and rocket troopers, 1 or 2 snipers, and 3 mounted machine guns that are you by the infantry. There is also some mines on the ground. After I kill everything, I found the hidden passage behind the parked tanks, and went in it. It brought me underground and to the other side of my tank and the gate that the tank cant break through. There are three places that the code can be used (the code may be different for each) but I don’t know where or what the code is. Can someone help? I am determined to beat this mod.
27th September 2006
Ok. Nevermind the last post…I found a walkthrough.
Although…I still need help because the walkthrough is wrong. This is probably the last time I will be asking for help in the mod though.
OK. In the part with the tank you get stopped because of 2 closed, large doors blocking the way. If you walk through the door to the left there is a sniper at the end of the hall. After I take him out there are 3 doors to the left. The first one is the only one I can go through. There is an annoying switch puzzle in there made up of 3 by 3 buttons. The walkthrough numbered the buttons like this:
1-2-3
4-5-6
7-8-9
to make it easier. They said to push the buttons in order of 7-6-1 from the beggining and the other 2 doors in the hallway should open. They don’t. Please help!
30th September 2006
OMG! This is one of the most confusing mods I have ever played (especially because I don’t speak french and the patch would’nt work) but I finally beat it. I know it’s amazing that I was able to so just let it sink in.
6th October 2006
So far this is my favorite of the mods I’ve played. IMO it surpasses Half-Life. It can be very tricky. Not in an unbalanced way or like many other mods that are overly difficult just to be annoying. The challenge here is through honest, masterful design.
14th October 2006
Rating: 5/5 + Excellence Award
Good: Everything is completely new; Cool ‘flashlight’; Decent story.
Bad: Incredibly difficult; Dialogue in French.
Review:
Well, now that I finally got around to playing Invasion, I wish I had done so earlier! This mod is a lot of fun. First, I’ll say this is the first mod to be played via Steam, and it went fairly well I think. At least I didn’t screw up! Anyway, I’ll start with the story.
You, Gordon Freeman, decide not to work with the G-Man at the end of Half-Life. Right before the G-Man teleports you away to the land of the Grunts, you step into a portal created by some rogue scientists hiding in another part of Black Mesa. When you recover, you find yourself in this remote part of BMRF with many scientists and an occasional Barney. From here, you learn what has happened. Suddenly, the secret is broken, and the military finds this hidden part! Now you are running for your life. Much of this is a well done scripted sequence, so you get to sit back and watch it.
Invasion is all new. Not just a new model here, or enemy there, but nearly everything is new. There is a new HUD, all new weapon models, some new textures, new sounds, etc …Definitely a lot of work has been put into the mod. The models aren’t super-high poly, but they are much better than HL defaults.
Another interesting feature is the flashlight, or lack of. Instead of a flashlight, you are given a lighter, like a Bic. This is pulled off very well. You even have to strike the primer a few times to get the flame sometimes, and it won’t work underwater! I really liked it, and it should be noted. Another unique item is the infrared pistol. When activated, you can see soldiers through the walls as a cool shade of red, much like an infrared device would show. The game play is excellent, with at least 8 hours of playtime on the medium difficulty setting. There are numerous obstacles you must negotiate, and all are challenging.
For the negatives, I will tell you, this mod is incredibly difficult. You will mangle your quickload key, I can almost guarantee it, but please don’t give up on this mod. Its a lot of fun, and just when you think its over, its not. Second, while there is a language selector (see below), all the dialogue said by the scientists is in French. But rest assured, there are captions in your chosen language.
Something I didn’t really like was the language selector. While its much better than having to try to translate French, it was just a bother to me. But there are 4 languages to choose from, so you should have no trouble understanding the story in your native tongue.
15th October 2006
wow 61 posts and counting. thanks christen for the hint on the tank. thats why i came here.
this new way of a mod is le perfect. great sofar. oh, i had no trouble clicking the english subtitles and voices. viva le half life 1.
16th October 2006
I wish I would have known what was going on; I mean I could figure it out, but I love knowing every detail. I think I’m going to play it again when the reflux version comes out.
20th October 2006
Ok I’m stuck at the 9 number puzzle and I’ve entered the 719 code many times but is does nothing?
20th October 2006
what map number is it?i’ll check tonight if i know what map.played it allready but i forget where is where
25th October 2006
I said earlier (I think so don’t verabally rape me if I’m wrong) that 719 does not work. There is more like 10 or more buttons you have to push in order to get it to work. Just look at what button does what and figure it out using logic.
27th October 2006
yea i have reloaded a save from just before i get to that part 6 times and 719 does not work.I’m not even sure what your supposed to do.are they supposed to be all yellow or dark?
maybe i should check and see if everytime it loads up the map it’s all random settings on the puzzle so its different each time?
the french and spanish walkthroughs are no help either cause translator aint worth a crap and they say 719 also
27th October 2006
Let me know if you find an answer sorry logic does not work either not going to spend hours trying to figure it out have more mods to play going to delete thi one
28th October 2006
Hi. I’m stuck in the location where is the first tank. I hop in but can’t move… only shoot. Is this some kind of bug or something? Thanks for any reply.
A.
28th October 2006
A.: the answer was on post number 39…
28th October 2006
The answer to post 69 was on post 39.
28th October 2006
sorry to hear that you got stuck at the first tank. i to ran into the same problem. with so meny posts on this mod, a great mod by the way. i will save ya some reading.
you must not die when you come in to the area where the tank is. you will have to load a saved part before the hallway were the game loads that map and before you open the door. it is a known glitch. i found out by reading all the posts. but, now i have saved you to fight on. hehe.
good luck.
29th October 2006
john:
Is it possibly caused of “GOD” mode? BTW thanks for your reply. 
I didn’t die of course because I can still walk… I suppose.
29th October 2006
Nevermind – I loaded previously saved autosave and everything is OK. Thanks again John.
1st November 2006
OK. Another annoying situation – 9 yellow buttons. What I have to do? Help somebody… please.
1st November 2006
If you find the answer please post it I was going to delete the mod but it’s to good.
1st November 2006
Ltemup:
I won’t find anything – I’ve tried everything – It’s worthless – we need somobody who knows what to do.
1st November 2006
Thanks anyway it’s been posted a few times here but nobody knows the answer:(
1st November 2006
I have played this mode at least 3 times, now.
I always solved the puzzle myself, but but never wrote down how I did it.
It never took me more than about 10 minutes to solve it.
My point is that it is feasable, it should not be a reason to delete the game.
1st November 2006
what map is the 9 yellow buttons on?
1st November 2006
l3m14
i tried to load it today and figure it out using:
· botón 1 => activa / desactiva botones 1,2 y 3
· botón 2 => activa / desactiva botones 2, 4 y 9
· botón 3 => activa / desactiva solo el botón 3
· botón 4 => activa / desactiva botones 2, 4 y 8
· botón 5 => activa / desactiva botones 1, 5 y 6
· botón 6 => activa / desactiva botones 1, 6 y 8
· botón 7 => activa / desactiva botones 3, 5 y 7
· botón 8 => activa / desactiva botones 5, 8 y 9
· botón 9 => activa / desactiva botones 1, 3 y 9
since if i read the walkthrough right they all need to be yellow.
But when i loaded it up to play it kept crashing saying it couln’t load sounds\sentences\blip.wav the sentences folder doesn’t even exist.time to reload the mod i guess.maybe a steam update screwed it up.
1st November 2006
ok, it seems you have it. i keep my old half life one (sierra)in the computer to play these mods. i dont use my steam account with half life steam. sorry you are haveing so much trouble, i like this mod and wonder did the developers make any more. good luck and feel free to post if you have any more troubles..
2nd November 2006
This mod is incredible – from one stuck to another!
I’m in the location with assembly lines and I found some control panel with lever but I don’t know what is it for. Please post somebody what I have to do. Thanks.
2nd November 2006
Thanx to a fellow Canadian over at DSLReports named Icxis,we have an answer to the puzzle
7-6-1
5th November 2006
Andyno check your save list and see what map name it is so I can help.
5th November 2006
andyb:
It’s “l4m2″…
5th November 2006
by assembly line do you mean the conveyor belts?If so you can change directions of the belts by using the console infront of you.The walkthrough explains what to do
5th November 2006
andyb:
Of course. I know I can change direction of the belts. But I’m already beyond this point – I’m meant control panel with lever (for screenshot visit http://img292.imageshack.us/my.php?image=untitledxg6.jpg). BTW – where is the walkthrough you’re talking about?
6th November 2006
I havent checked yet but by the looks of it ,it is the lever to start the trash compactor that will blow a hole in the floor if you did it right.
walkthrough is Here
6th November 2006
andyb:
Thanks my friend, that walkthrough is quite useful.
29th November 2006
a interisting note. if you smash the boxes in the trash compactor the tnt will not blow a hole in the grate. you have to start over before you got courious and smashed them.
also i am now in the part with the girguantion, i have no gernades, no cluster gernades, but have a red mark for the cluster. the game wont let me pick up the explosive gernades and i have no tab on 5 i think for them anymore. any hints?
29th November 2006
I would have to replay it to give a hint.got a map name/number?Should be in your save list.Its been awhile since I played this.
29th November 2006
sorry andyb, i thought i put one i am on map 14m4. thanks. i just dont see why the explosive gernades are no longer on the weapons list.
30th November 2006
hey, everybody. you can sleep good tonight. i stoped the invasion. hehe. man what a great mod. i give it 5 crowbars.
i would love to see a opposing force mod done by these guys. thanks again. it was the greatest.
30th November 2006
PHEW!

Hello guys
This one is Great mod But I Read The Comments and I Think Very of Gamers had Problem With it and They Discover Very Bugs in This Mod just Like my Problems! I Download This Mod But Can’t Play it Because after I Start The New Game it Crash to Windows in Loading Screen. I Update My HL1 to Vesion 1.1.0.6 but I Think his version is not Currect to Play This mod. But I can’t Read or Write French so I can’t Discover The version of HL1 That Require to Run This mod. Please Help me!!
14th January 2007
Come on Guys!
Please Heeeeeeeeeeeelp meeeeee!!
I Gonna Die!!!
14th January 2007
Update to a newer version.1.1.0.6 is a decade old.
version 1.1.1.1
15th January 2007
Thanks for your great help but now I have another Problem!
when I Update my Game and then Run it, this error apeared : your Half life\executable has been modified. Please Check your system for viruses and then Re-install Half Life.
Please Help me!
15th January 2007
Did you run a virus scan?Having a virus scanner on your pc doesn’t count.Use an oline one first(http://housecall.trendmicro.com/).I’m not saying thats the problem but it may help.After you run it I will offer as much assistance as I can.The only other options are to reinstall or download steam and supply the key.
15th January 2007
Has ‘noclip’ been disabled in this mod, or is there a different way to use it? I keep getting “stuck” at the top of lifts. In other mods I would just noclip myself free, but in Invasion noclip crashes the game. I tried some other commands- ‘notarget’ and ‘god’ also cause CTDs, and it happens in both Steam and non-Steam versions (playing v1.1.1.1).
15th January 2007
Invasion has an anti cheat built in.To get around this open the console and type testmode
Note that if you save the game and try to load it later it will crash so you must start a new game enter testmode then load the save.
