literally a fork of the Source SDK Multiplayer but with perks and kinda optimized (half-life 2 deathmatch on steroids)
so xen source is an epic mod for Source SDK Base 2013 Multiplayer, that adds perks like gamemodes and kinda optimizes the game in a bug-way. probably Rafasn's Mod will use the fork because he's currently making RMOD 13.
GAMEMODE EXPLANATION:
SANDBOX & DEATHMATCH - no need for explanation
ARSENAL - you get 1-4 weapons and its basically a FFA
CHAOS - 1 hp, speed and only crowbar
