DAY 1 of its release. And as for my best moments? well, let us say there are so many that I can't say. I play mostly the PC version these days which is halo 1. But the best moment yesterday... when I spawned, saw the reds running for my flag in Bloodgulch and no scoped... and somehow, got a triple headshot with a single bullet.
Lets just say I felt so boss.
