I have a Friend who is a "Pretend Glitch finder". He goes "lemme go try something" Then I leave him alone, and suddenly he comes up to me with a friggin gravity hammer and chops my head of.
How could you guys forget the infamous noob? That one kid who will go "I'm new to xbox live, how I switch weaponz" usually he/she loses the match for your team.
hoestly, i think i might me a 10th type of gamer you dont want to have on your team... teh N00BZ! i.e. someone who just got the game and is playing against vetren players. + i blame the f***ing lag in counterstrike
I've played as the Drill Sergeant before. We were doing a Vidmaster achievement on Halo 3, involving 4 player co-op. I got the red elite, my friend got to be a blue one. I prefaced every comment to him with 'As your commanding officer...'. I laughed my A-fiftyfive off at that one. Also, you didn't go far enough on the lone wolf - The jackass that will betray you just for the sniper rifle.
You know I'm a bit of every one of these, except greifer, But i remember one time i accidentally ran up to a guy on my team and blasted him in the face with a shotgun. I forgot i was on the blue team.
