The Halo 5 multiplayer beta will be accessible to a limited few tomorrow, ahead of broader availability.
Halo 5: Guardians will open its doors to Xbox One Preview Program participants on Friday December 19, US time.
According to MP1st, these lucky few will have until December 21 to get a head start.
Those of you who scored beta entry through picking up The Master Chief Collection will have to wait for December 29 to join the fun.
Don't be miffed; though; the Preview program is a pretty limited taster, whereas the full beta will rotate content during its three week run, eventually showing off seven maps and three game modes.
Here's a trailer to get you in the spartan mood:
