There are some pretty cool spots left. There are jumps and strafes and whatnot to do, but i have to say that i'm not really cut by the recent patch on elevators. If you want to camp, i just stay in open areas. I know that you are probably thinking "WHAT", but hey, let me continue. I basically try to camp where everyone runs by, typically in the open. At MOST there are three different ways to look, but most of the time just 2. If you are like "oh, someone will knife me in the back" then keep looking at where your teammates are spawning. If they are close, then its sweet. If its only on one side, watch the 'exposed' side. If they are spawning in a completely different area, i hide. Then i wait till i can see my team edging closer towards me. This is typically when people start heading the other direction, so you can nail your enemies in the back.
IN SHORT: you can do jumps, strafes and SOME wall-breaches (dunno what ones).
if you get bored, just see how big a knife-streak you can get. Its always a challenge,especially on wasteland.
