This is your familiar Halo experience. The go to game types. Some of this stuff you should already be used to. If you like Assault Rifle and Magnum starts (and you will much more than you did the same in Halo 3, trust me), you should go with Slayer. Should be self-explanatory. Like the longer range game? Vote for Pro.
Youll also see a healthy mix of objective stuff like 1 Flag, Crazy King, Oddball, and, back by popular demand, Halo 2 style Three Plots, where teams must capture and hold a series of three fixed territories that can be subsequently recaptured by the opposition. The more territories you hold down at any one given time, the more points you are awarded, per second.
Youll also run into a little somethin somethin we like to call Covie Slayer. Elite on Elite evasion action. Do yourself a favor and cast your vote in favor of this at least once. Trust me.
