A closer look at Halo 4's Ordinance system, Infinity Slayer and Regicide
343 Industries have just posted an E3 multiplayer wrap-up, giving you the chance to see the new "Infinity Slayer" and "Regicide" multiplayer modes.
Thankfully, the video also explains Halo 4's new "Ordinance" system. Performing kills, assists or engaging in "style" gameplay (things like ending a kill spree, assassinations, or killing someone attempting to hijack a vehicle...) fill up your Ordnance Meter; when full, you'll be able to select from three randomly generated rewards: two weapons or one power-up. It's neat.
Look for Halo 4 this November on Xbox 360.
