Playing lox on gaming zone or whatever(you hosting):

Launch your Q2 and set game lox then Hit F5 set your Death Match flags and hit begin,then all you have to do is hit the number keys because the new weapons are bound for you(just scroll the numbers)

Single Player:

Type these things in the console first: set game lox   set skill 9999 (so the monsters will be stronger)  then hit F5 and set your Death Match flags (like infinite ammo and no fall damage so on) then set it to co-op game and hit begin.
