Glitch: Tear gas:
In P.E.C. mode, reset your identity. Sell your frags and do not put skill points in anything. Buy as much tear gas as possible and equip them in both equipment slots. Get a friend and go the Green Team spawn point on Clinic in survival mode. Have one player sit in the bottom right corner. Throw all your tear gas on each other, then have one of the players look up in the air. Have the other player shoot the player looking up in the chest or stomach. The player that was shot should then shoot the other player in the head. You will also gain money.
