343 Industries has announced that Halo 3: ODST Firefight will be added to Halo: The Master Chief Collection on Xbox One and PC later this summer. You can see the teaser above.
If you haven't played it, Firefight is a mode for up to four players in which you fight against waves of Covenant attackers across a variety of maps. While the Halo 3: ODST campaign was originally added to the Master Chief Collection for Xbox One back in 2015, Firefight wasn't included at the time.
No further details have been mentioned for now, but we'll let you know when we hear more.
