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!
Because I'm a bonehead who forgot to remove a few gameinfo.txt entries, which probably makes the game crash on startup. This is supposed to overwrite the gameinfo.txt in your "sourcemods/Smod Standalone/mods/Smod40aq_Arcade" directory
