Chemical Existence is a Total Conversion type of mod, singleplayer. It is pretty old, so the cutscenes are that greatly graphic wise, but it is So-So. Completley different weapons, so it can be fun.

Evilghoul :devil:

This was a very strange mod for me when I played it. All that custom work, but cant fathom the time and effort people put in, and to have it appreciated so little. Shame.
It's fun from what a remember, a little unfair.
And gets strange as one part the rooms are made of people textures. Ending was a bit depressing as well.
I'll give it another try, if this glitch people seem to have right now gets cleared up.

To fix the not being able to move glitch:
You installed the the steam fix to the wrong spot. install it to a folder on the desktop and then copy all the files and put it in your chemical existence folder

I can't adjust, or even see the keybpard controls in the games options. They simply are not there. I reinstalled it several times still all the keyboard controls are missing.

Also, as someone else mentioned, if I untick reverse mouse it disables everything other movement in the game. Altho I haven't been able to really play it since I can't customize the keyboard controls.

Is there a fix? I don't see any.

I think i found a bug here, for those who have lost models from Chemical Existence like soldier.mdl from the 2nd map or something else, i think the mod wasn't loading the models from the paks, using GCFScape or PakExplorer, extract all the models, sounds, and sprites to the mod folder, that should help, if it doesn't, maybe you have to redownload it.

The level design is mostly bare open spaces, with blocky textures... and felt rather random. I would have so preferred if the mod stayed in the urban type of places because it was so short lived. But the characters look good (and most…
