I used to play Halo like nobody's business. Halo 3 was one of the first games I got for my 360, and it's easily my favorite from the series. God I have so many memories from that game... I was SO competitive.
Im picking up the halo master cheif collection this Nov on xbox one it includes the halo 1 2 3 4 (all the multiplayer from each game yes even halo 2's original multiplayer modes) and the beta code for halo 5!! 343 has givin each game a huge hd make over without tarnishing the gameplay (halo 2 will still have its famous glitches that were in the original multiplayer) I think its a no brainer purchase.
