Wasteland 2: Director's Cut (EP)

Friendly fire is possible in this game, especially when using Shotguns and Heavy Weapons or firing SMGs/Assault Rifles in burst mode, when the enemy you're shooting at is next to your team-mate. When your team-mates go down either via enemy attacks or friendly fire, they collapse and go into an unconscious mode. During this mode, your team-mate will start to either bleed to death or slowly regain consciousness, but otherwise remain out of combat, with a special red (instead of green) health bar. Attacking (accidentally or not) your downed team-mate until that red health bar goes to zero will kill him/her and pop the trophy. This trophy can and should be combined with [B]Skin 'O Yer Teeth[/B]. If you're having difficulty with this, try increasing your game difficulty as that increases friendly fire damage.
