THE BEST BUNGIE HALO EVAH!!!
...yet sadly the last... but with weapons, gameplay, and the new multiplayer firefight, It's Like ODST with Halo 3 On steroids!!! Grunts are harder, Elites dual wield needlers, and best of all, ordnance up the wazoo!!!
By the Time the next Halo comes out (from microsoft) we'll probably have forgotten that bungie stopped making halo.
