8 Co-Op Video Games That Let You Be An Utter D*ck!
3. Any Game With Friendly Fire
If there are three words absolutely guaranteed to annoy any online teammates, they're "Friendly Fire On" as you simply know that whatever title you're playing, someone at some point is going to lodge a bullet or arrow right in the side of your temple.
This mode is meant to be for well-oiled teams, who clearly understand what role each person has to play, yet in many cases, this will result in a squad wipe as your own team drains your health sometimes without even realizing it.
Take Vermintide II for example, which offers some pretty distinct classes. Some are melee driven while others excel at ranged. However, picking out your teammate from the pile of rats swarming them can sometimes be impossible, and so you either get called a dick for shooting and hitting them by accident, or you get called a dick for leaving them to their fate.
Teamwork at its finest.
