ICE HL2 Source code for learning and modification.
ICE Source code has a lot of edits to the Half-Life 2 code including new game features such as snow foot prints, addable/removable helmet, enemies who's skin glow different colors, and many new weapons. We make our code available here for everyone interested in code to learn from what we have done over the years. We make this available with no intentions of guiding you through it by hand, for that you are on your own.
Thank you for this! :D
I wish more Modders Released the Source Code of their Source & GoldSrc Mods.
I should note, searching "icemod" in the code will help find some of ICE's code in there.
For those of you that prefer using Git I've prepared a repo here: Github.com
