Though some of the footage may have already leaked, Microsoft will officially reveal Halo 5: Guardians gameplay tonight during the HaloFest livestream on Twitch. The event kicks off at 8 PM Pacific / 11 PM Eastern, and you'll be able to watch directly in this post--we'll add the video as the event draws closer.

GameSpot editors also recently got to play Halo 5 and we'll have our impressions for you to see at 9 PM Pacific / Midnight Eastern.

In addition to hosting the first Halo 5 gameplay footage, tonight's HaloFest stream will include developer interviews and a first look at Ridley Scott's Halo: Nightfall live-action series. This all leads up to the launch of Xbox One game Halo: The Master Chief Collection's release at midnight tonight.
