Length: 2 maps + 1 unfinished, version 1.0. Please read the description for instructions on installation (it requires spirit installed).
Install the latest version of Spirit of Half-Life (spirit.valveerc.com) or here on modDB. Make sure its a download with "no Source Code" because that way its compiled for you to be used with mods.
Copy the "Spirit" folder into your Half-Life folder and rename it to "coldexv1". Then copy all files from this archive to the "coldexv1" folder. Overwrite all folders and the files called "liblist.gam", "titles.txt" and "skill.cfg" only. To play the mod, go to "Custom game" in Half-Life menu, choose "Cold Experiment" and click on "Activate".
Readme:
This is Cold Experiment episode. This version was cancelled, new version is in development. You can find source files of what I managed to make in the "maps" folder. Episode can be shared, but I don't wish it to appear on any sites for download. If you want to place it on your website anyway, please contact me on "jiri.polcar@seznam.cz". If the episode doesn't work for you, you probably don't have Spirit installed. You can get it here: spirit.valveerc.com. Don't forget to download the latest version.
