We though we would show you just how the campaign has changed with a sneak peek into the first 20 minutes of the game. The gameplay you are about to see has been recorded directly off an Xbox One and is all in-game footage. It is of the first mission in the game, Osiris, that sees Spartan Locke and his team, Osiris, head into a Forerunner structure to find and extract the UNSC’s most wanted criminal, Catherine Elizabeth Halsey.

We have much more in store as the multiplayer portion of the game goes live for press today. We will show off some of the best maps and guns you can find. Halo 5: Guardians launches exclusively on Xbox One on 27 October 2015.
