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!
Fixes crashing on startup for users without widescreen monitors. I have absolutely no idea why the game crashes like this to begin with, seriously. But oh well, here's the fix! Extract the contents to your "sourcemods/Smod Standalone/mods/Smod40aq_Arcade" folder
This fixed my startup crashes on my 16:9 monitor too, weird
