Gang Garrison 2 is a free multiplayer ‘demake’ of Valve’s Team Fortress 2 started by mrfredman and MedO with many developers later adding new features. With all 9 classes, many different TF2-inspired environments, and fast-paced, team-based, multiplayer gameplay represented, GG2 is the premier TF2 tribute-parody-alternative.
P.S the original TF2 game is free to play on Steam, just in case you didn’t know.. 😆
