Halo 4 Stars The Forerunners

Microsoft’s E3 Briefing started off with Halo 4 gameplay and Chief facing off against the Forerunners. Chief used some guns from the mysterious race and showed off a new grenade type that disintegrates enemies. Cortana notices the Forerunner tech when Chief picks up a rifle from a monstrous Tron-like beast.

The UNSC peaceship Infinity crash lands on the planet and right before Chief can go after it, a giant ball comes out of the ground and flies toward the downed ship. The Covenant on the planet, as well. Still, it looks like the Forerunners are the real enemy here.

Anyone else getting a Metroid Prime feeling?
