camping will get you killed in this game.
Camping in the exact same spot yes will get you killed. Guarding an area is an effective strat. I have ghosted plenty of people who were trying to dislodge me.
I did like halo's theater, and hope something similar will be implented in brink, since we need to record our badassery.
As much as killcams can be good it would be more counter productive in Brink.
