Microsoft finally gave us some video of their latest to the Halo franchise. Anyone watching the live conference (shown on a number of sites) already got to see it earlier today, but for anyone late to the party, here's your chance! The start of a new series called the Reclaimer trilogy, Halo 4 is being developed by 343 Industries. As you see in the trailer, the Covenant returns, but they won't be your only problem. A new enemy is revealed in the trailer using weaponry that Cortana believes is forerunner in origin.
Halo 4 sees a return to gameplay as the infamous Sparta John-117. Cortana also appears to be...spastic. Which should make for some interesting gameplay.
