They had gravitational effects AND perpetual levels. Meaning if you took off running you could go forever. No borders on the levels. Snipers paradise. With enough patience you could circle back around anyone anywhere. Sometimes I did nothing but run for 20-25 minutes straight. By the time I got where I wanted to go there'd be about 15 minutes left in the match and I'd STILL win because I'd get 20 points per kill. I'd be so far out no one could spot me even with binoculars. They'd need the high-powered scope on the same gun I used.
that sounds awesome, i love snipping
