Warzone is 24-player Halo 5 multiplayer

Microsoft has unveiled Warzone, a new Halo 5 mode for up to 24 players.

Based on the brief reveal during Microsoft's E3 2015 press conference, Warzone sees two teams of players fight against each other, with computer-controlled enemies thrown into the mix on huge maps.

We saw ground and air vehicles, mechs and all sorts of carnage. Apparently the maps involved are four times the size of any previous Halo map, which sounds impressive indeed.
