Microsoft dropped some serious Halo 5: Guardians news during the company's pre-E3 press conference, including a new trailer of one of the game's online mode.
343 studio head Bonnie Ross opened the press conference, noting that it's built from the ground up for the Xbox One. A shorter trailer led into an in-game live co-op demonstration, and a diverse cast of characters. There is a substantial graphical jump from previous Halo games. You'll also be able to revive your teammates in co-op.
We also learned there is a 24 player multiplayer mode called Warzone with AI controlled adversaries, and maps that are four-times the size of past maps. Josh Holmes of 343 Industries called it "the most ambitious Halo campaign to date," offering seamless drop-in, drop-out co-operative play. You can watch the trailer above.
Single and multiplayer modes run at 60 fps, with an engine built for Xbox One.
