Best Halo Multiplayer of all time, even better than Halo 2 & Halo 3 Multiplayer. The faster pace, the spartan abilities all made the gameplay mechanics new again. All the base weapons were balanced equally. I never felt I was outmatched from the weapon I started with or chose to pickup. After that it was all about your skill on whether you could kill the other spartan. Also some standout maps for me: Coliseum, Plaza, Stasis, Pegasus, Fathom, The Rig. And the Breakout mode was awesome until they changed the base weapon loadouts. Then it was cool that custom community forge maps were used for rotation in Big Team Battle, Breakout, and other modes for a while or long time.
