WoW!
I played the Timeline II and III levels and I’ve noticced they got better as the game progressed. The locations in Timeline III were probably the best I’ve ever been to in a half life mod.
Without giving away too much there is this one part where you can go to four timelines (really five, but i’ll leave that a surprise). set in a future Lambda complex. Your first choice takes you to HG Wells and the story that the Time Machine has brought to us over the past century. There is one bug here though i encountered where your weapon will have no ammo. Simply quick load the game and that bug should be fixed.
Then there’s the year 2019 which is basically modern and nothing too fancy about it. But the other two locations just capture the mind and your imagination so much it could be a movie or a book. You go to the year 5 billion AD with the sun a super massive red giant and 20 billion years AD. And once you beat all that you’re still only half way through the mod!
The mod’s cut scenes were nicely done but there were a few times that I wish they had had a cut scene or two that it was kind of confusing. Especially with the chose your time zone part. I didn’t know if I had completed that mission or not. Though lava rushing after you is a good hint that that mission is accomplished.

anyone else have a problem with the game crashing on map change from dark11e to f ? thats the spot where after breaking a case open getting the goods and the floor gives away you have to crawl through a pipe.when dropping down the pipe it crashes to desktop.does it in steam also.i tried just manually loading the map but it crashes then too.

I have enjoyed Timeline 1&2 so far with not much problems, only getting stuck on elevators sometimes! but I’m in Timeline 3 part 2: The cry of Mankind and now the comments are in some different language!! Is the rest of the mod like this??? or is there another version in English?? I printed your walkthru, just in case! I don’t like using them, makes it to easy, cause I like to challange my old Grey Gamer Mind!! Since I don’t eat oranges, I use a large wooden mallet on the back of my head when I get stuck!!

no idea what you mean. part 2? darkness is in another language for text.
16 October 2006 at 4:34 am
I went by the listing in the Timeline 3 walkthru it says what I described above, BUT when I looked at my save map list it says darkness, take a look at the walkthru. But my same question, Is the language different in the rest of this mod??? I’ll get thru it but it’s annoying when you can’t understand the message! Hmmmmmm maybe the old dog needs to learn some new tricks??

well i extracted the maps from the pak file and tried to run a viewer on map dark11f but no go.seems to be errors in the .bsp.worked fine on other files.couldnt export to a .map and rebuild because of the errors either.what a pain.

Whoops, just posted on the walkthrough instead of here. Sorry!
I crash in exactly the same place, just as you drop down the tube after the floor has fallen away. I tried skipping onto the next map, but that didn’t really help in any way whatsoever….
Pity, I was really enjoying this one, just as the previous two.
Any suggestions please?

if you find an answer let me know.short of finding someone with an original pak not corrupted I have no idea.

The download at “the Archive” isn’t corrupted,at least not at the same place that the one I got from here is. The zip has a different name though, as does the folder in it.
But on the plus side the text referred to above is in English!

I’m 99% certain that I also have that file:
http://www.filecloud.com/files/file.php?user_file_id=145975
It’s the same name and size. I’ve added it to the main post.

The original download was 38Mb and the one you’ve just linked to is 40.6Mb…I wonder if there was something missing?
At least its working now!
And once again, thank you for an excellent site!

I must say I dont think I could of finished this mod without the walkthrough.I really enjoyed it and the length of it was great.Almost like a whole new game.
26 October 2006 at 1:47 am
Having the same crash when the floor drops out going inside the pipe to the drop off and game quits
26 October 2006 at 1:16 pm
do the same thing you did with the one you have installed now.just over write the files with the new ones.
26 October 2006 at 1:31 pm
Thanks again!!

hey i’ve downloaded the 3 timeline episodes yesterday, and i’ve won 1 & 2 i found the improvements in each episode very nice you learn as you go on into making this i like the detail level for some things and others..
im playing timeline 3 im at the begining of the second episode, and i wanted to share the fact that i have actually (this is for the ppl who played this) i still have barney with me, (yes the one from the begining) it’s a loler and well i wanted to say thanks to this page that has prove to be valuavle one more time to make me enjoy some good games, with all that sayd i think this is a mod that no hl-gamer should miss.

sorry fot the double post.
you need to get a keycard from the room were there are two elevators, the panels on the walls are actually doors check the guide it has pictures, with that keycard you activate the satelite or something and then you can press the buttons in the control room.

Finally finished all tree Timeline mods and all of them are great in places hard but playable.
Great gameplay and story I can only say

quality mop/design great/good balance/hard jumps/lots of going tracking/confusing at times.
From the design side this is properly the best of the 3 in the series, however, I find it contained too much back tracking making the mod very confusing at time, such that I did not enjoy 3 as much as 1 & 2. But it’s still a quality mod with design great, good balance gameplay if on the hard side with some very difficult jumps.
Overall the Timeline trilogy ranks among the best all time HL1 custom games and if you have not played them you are missing out. I am ranking the whole series here.

It’s astonishing that the Timeline series isn’t better known – I have played over 100 HL1 mods and this one has only just hit my radar! It is a towering achievement – one of the very best mods around. It is well worth playing Timelines 1, 2 and 3 in sequence as the very ingenious story unfolds throughout all three. The gameplay is really tough in places, both in terms of firefights and puzzles. I usually play on “Hard” but did the three Timelines on “Easy” – it’s that tricky – and had frequent recourse to the excellent walkthroughs. This mod is engrossing, enjoyable, clever and has plenty of humour. 5/5 from me.
