From the PlanetXbox360.com feature preview:
"Love it or hate it, the Halo franchise is, for lack of a better word, one of the main pinnacles of first-person shooting gameplay, across the board. It's easy to point out that the series would probably struggle on the PC, that nothing about it is particularly realistic, or that while first person shooting gameplay has progressed into the realm of role playing games, team-based zombie killing, plot-based multiplayer, Halo has largely ignored most of those gimmicks. Sometimes it can even feel a little vanilla, that underneath all of those bright colors and crazy weapons is a standard feel-good shooter that will always do what it does very, very well. From four-player online or couch play co-op, to the fantastic 16-person multiplayer endeavors, the game is tightly balanced and infinitely malleable."
