Take any multiplayer FPS with a capture the flag,or destroy the objectif mode.
Now have all the guys on one team spawn camp the other team.It really pisses me off when you spawn and receive:
1 rocket
2 or 3 sniper rifle bullets
50 machine gun bullets
Seriously,I just came from a BC2 server where there even was a blackhawk(complete with side mounted miniguns) parked in our base and a uav hidden in a building.Queue in the ridiculous idea of giving every sniper access to artillery,not linked to one another so the cooldown perdiod is unique for every sniper,of course, and you get the most infuriating match I've ever played.
Needless to say,changing team and team killing every one of those game ruining bastards with C4 was satisfying,so I'm mellowed out now.
