Crysis 2. Rooftop level. FFA. Just grabbed a shotgun and went around, cloaking, sprinting and armoring up in various situations, always picking the best tactical option in terms of abilities and positioning, and utterly destroyed my competition. I think I was around 20 kills ahead of second place, with only 1 death to my name.

Just a phenomenal round. I couldn't believe it. I liked Crysis 2's multiplayer, and I was much better at it than, say, Halo or COD, but even so... I was never that good. xD
