My worst deaths are in Halo combat evolved, with map modded servers where u cant see the others, or only high in the air jumping... in air...

(That is if you dont have the mods installed, Halo mods suck imho xD)

And maybe a camper in F.E.A.R hiding in a room, thats triggered with 5 remote mines xD u run in or by and B........M!!
