Smod Arcade is a remake of The_Commander's long-dead SMOD: Deathmatch, it is a Singleplayer mod that aims to emulate a Multiplayer experience. Arcade is heavily RNG-based, every match starts you off with random weapons in a random map with 1 of 4 random gamemodes to play, with more being developed off and on!
Initial Arcade release, with 4 different gamemodes and 70 2006-era maps, including the maps from HL2: Survivor
