Halo 2 (2004)
Following the Halo-obliterating events of the first game, this sequel put players back in Chief's Spartan battle boots, but also let them tear things up as disgraced Covenant Elite Commander, Arbiter. This decision as well as the campaign's abrupt cliffhanger divided fans, but the new ability to dual-wield death-dealers and play online with friends overshadowed Halo 2's shortcomings.
