Sci- Fi Single Player First Person Shooter Games Half Life 2 Doom 3 Far Cry Unreal UT2004 Quake Mods
About

Story
Chemical Existence puts you in the role of Reece Max whom simply is in the wrong place at the wrong time. He gets mixed up with fighting gangs, evil corporations and mutated creatures…

Gameplay
Chemical Existence will be based on fun rather than realism; (like we said before… so many other games do that so well already). You will have to think an extra time before you attack your target, since every enemy acts different, some might even decide to help you out…

Levels
Chemical Existence features many different styles and environments. Fight your way through cruel ghettos, get through china town and fight off gangs in the deadly sewers beneath the city. Cross the river by boat, the woods by jeep and find your way to the mysterious chemical plant where strange mutated creatures roam free…
There are 11 unique and detailed levels in the final version.

Weapons
The weapons are both familiar “classics” (implemented in new and unique ways though) like our Sniper rifle and pistol, and totally new inventions like the “Lump of wood” and the Assault cannon. The weapons aren't 100% “realistic” (so many other TCs/mods/games are doing this fine already), all the weapons are instead intended to be useful, and most of all. Fun to use!

Enemies
Chemical Existence includes a lot of different enemies to give you a most challenging experience. Everything between street gangs, snipers and paid of police officers to mutated creatures or humans. You’ll also encounter evil corporation soldiers and agents along your way. From the moment you start and to the very end you will have to change tactics for each new enemy you meet. The enemies take advantage of their environment, so watch out! Also if you're playing smart you might not have to take on all of the enemies… If, for example you meet a gang and some police officers., why not just let them fight it out among themselves.
There are around 10 totally new enemies, with tons of scripted sequences and animations!

Multiplayer
Even though Chemical Existence is mainly a single player experience, multiplayer won’t be forgotten. There will be some totally new deathmatch only levels for your enjoyment and you will be able to use all of the single player weapons to spread destruction. We also included several new player models.

    This is a nice one I played a while ago. It also has a patch to apply to it. At the time I played it, the latest patch was 1.0.1 (ce101), which I have in my archives. You may want to check the author’s website for that, and also post here the latest patch, whichever version it is.

  2. I’ve updated the post to include screenshots and other infomation, including a link to the patch.

    I have recently replayed it, there is a tip: at the begining, the playing area is WAY too dark. There is a ladder to find, which you CANNOT see with usual video settings.

  4. a really amazing adventure.

    Why is it that some I can never install some mods to the right place. And of course…this looks like one of the better ones. Someone please just respond cause I’d especially like to play this mod. No one ever responds to the other ones!!

    So Christian…u can see it in your steam games list? I cant. And when I try to play it from the game startup it says im missing something even though Ive downloaded it numerous time from numerous sites. I think it says Im missing the half-life.exe or something like that.

    Heyzors, I have a question for you, are you trying to run CE from the HL that’s included with HL2 or the stand alone HL from Sierra?? I tried installing it from my archive files and it worked just fine for me! I don’t think it’s made for the Steam setup??

  10. Christian 68 comments

    I do not use Steam, only the old fashion custom games….

  11. heyzors 6347 comments

    14th June 2006

    Im trying the one from HL2(although it isnt on the source engine). All the other games I play work in that folder and dont work in the Seirra one. Ill try Seirra now though and see if it works. Cross your fingers!

  14. heyzors 6347 comments

    14th June 2006

    Actually, Im pretty sure I have everything I need except the hl.exe. Does anyone know where I can get that? It didnt come with the installation of half-life from steam or chemical existance or the patch!

    15th June 2006

    Sorry to hear it still don’t work for you, I’ve got both versions of HL, that is the game of the year version and the vannilla version, and I found some of the custom games and/or maps don’t work with the G.O.T.Y. version!! Make sure you have the update hl1110.exe installed also! This site is a treasure house of great stuff, it’s a shame if you can’t enjoy ‘em!!!!

    Does anyone know what a PF file is? I think I found the files, but I’m not sure. I dont know how to open a PF file nor do I know what it is.

    I also want to apologize if I’m spamming. I just really want to play this game!!!!!!!!!!!!

    This is a new glitch in my mod experience…no keyboard response. I got it installed and went to options and click on the keyboard tab and the field is blank. No key controls are listed at all and I cannot move my character…the standard keys..w,d,s,a etc. have no effect. Any ideas?

      I had the same issue. Did you also install the steamfix? if you did, I found the instead of installing to my half-life directory, it made a seperate folder called username and put it in there. You need the steamfix because it has the config in it. Just grab the ce dir from username and put it in the half life dir.

  18. Christian 68 comments

    15th June 2006

    Missing or corrupt config.cfg in the mod directory?

    Check if there is one, copy from other HL folder is needed.

  19. heyzors 6347 comments

    15th June 2006

    I dont have one in the half-life folder or the chemical existence one although half-life works fine. I wonder whats wrong. Maybe its the startup but that probably isnt it. hmmm……….

    No config.cfg files anywhere in Half Life. What else can I try. I think I will delete it and reinstall it.
    Thanks for trying to help.

    I uninstalled CE and deleted the zip file and then downloaded it again. I installed it in the right directory as it is showing up in my third party games list. Then I unzipped the patch file and copied those files into the CE directory. I still have the same problem…no keyboard function.

  25. Christian 68 comments

    15th June 2006

    I have never used Steam, and do not want to for a few reasons, so I do not know the details of how it is installed, and therefore cannot help there.
    My installion is the original HL from very fist release, patched to last release for it, which did not include Steam.

    Th only thing I could sugesst, which may be inconvenient to you, is a clean reinstall of your copy of HL (NOT HL2), without steam if you can, patched to same version.

    16th June 2006

    Yes here is some good advice —> Stop trying to run the HL1 mods with the Steam HL1 source, in HL2 —> Remove your Serria HL1 and reinstall it and only run these mods from there!! I hooked up my “OLD” IBM Aptiva 400mhz machine, with only 64meg ram and they all run fine! this is the only logical advice that I can give you. Anyone else?????

  27. Carolyn 29 comments

    16th June 2006

    Heyzors,
    Any luck installing? I ran the exe file and it wanted to install it in Sierra. I didn’t do that but installed it in C:\Program Files\Steam\SteamApps\mysteamaccoutusername\half-life\ce
    It loads and runs fine except for one small problem…I can’t move my character and there are no keyboard controls shown in the options menu. Let me know if you get it installed and running. I’m so bummed bacause I really want to play this mod.

  28. heyzors 6347 comments

    16th June 2006

    Carolyn, at least you can play the mod. If I were you, I would reinstall the game. Before you do that turn your brightness up because I remember hearing something about need a high brightness at the beginning of the game. If not, try reinstalling it.

    I on the other hand have come to the conclusion that something is wrong with my computer. If anyone has any ideas, please post to help me (and Carolyn if my 2 suggestions don’t work)!!!!!!!!!!!!!!!!!!!!!!!

  29. heyzors 6347 comments

    21st June 2006

    A.I. Just for the record I dont have any files for the sierra HL and I dont know where to get them. I only have it for steam.

    YAY! I finally figured it out. Each person downloads files differently on their computer so I downloaded the mod on my friends computer and sent it to myself through x-fire.

    this mod is crap. the enemy AI is terrible. you shoot them and they just stop and stare at you. some of the characters were horribly done. wolfenstein weapons were cheesy. a diarrhea mess of a game. the developer should have spent more time on it.

    hey i had the same key problem so i placed my own .cfg file in the CE foldier. now 10 cookies to the one that tells me why is the .cfg canceled when i un-invert the mouse, or even why if the .cfg has a regular mouse setting the game invert’s it, plus adds 20 of sensibility wich i thik is just to add up to teh flavor… in enycase the key problem is solutioned by plasing the hl.cfg file in the ce foldier and then on the consele just put “exec hl.cfg” (hl is and example my .cfg is named NoD.cfg) now if enybody can answer my question i will feel happy :p oh by the way the “why do you hurt the poor box” it could be solved by using an unbreakable box ( and i think i played this before long long time ago.

    With PakExplorer, go in the mod folder and open ce\pak0.pak. Rename or delete the \gfx\shell\kb_act.lst file.

    As a second option, you could do a search on your Half-Life folder to try to find a kb_act.lst file from another mod. Create a folder in ‘ce’ called ‘gfx,’ and a folder ‘shell’ inside the ‘gfx’ folder. Copy kb_act.lst into ‘shell.’

    deleting “kb_act.lst” did the trick. Thanks a lot, Gilfrarry

      There’s a file now, but until it’s updated you’ll also need to get the patch at GameFront.

      You can also get the walkthrough at the Internet Archive.

    I am also having trouble with playing this mod. I have no keyboard response and cannot change the input, as nothing is there to change. I have the patch for Steam as well. I would do as Gilfrarry said, but for some reason I can’t delete the ‘kb_act.lst’ in Pak Explorer. I can find ‘pak0.pak’ but whenever I try to open it, it says that Pak Explorer has ‘encountered a problem and needs to close.’ Basically, it crashed, and I am unable to delete the file. Any suggestions on what to do?
