Microsoft has delighted gamers by surprise releasing Halo Infinite in multiplayer mode yesterday.

The game was originally slated for a December 8 release, but Microsoft announced the release during Xbox’s 20th anniversary stream for the original Halo, which was released November 15, 2001.

The game is officially still in beta mode until December 8, when the full game is released. But all your progression in the beta model will move across to your full game come December.
