Halo 3: ODST launched in 2009, developed by Bungie as a spinoff game in the iconic Halo franchise. The game is set during Halo 2, telling the story of a group of Orbital Drop Shock Troopers (ODSTs) and their fight against the alien Covenant in the city of New Mombasa as their mission suddenly changes course.

Helldivers 2 looks set for an unlikely Halo crossover after a new trailer teased the arrival of the ODST. Arrowhead's hugely successful PC and PlayStation 5 third-person shooter launches on Xbox Series X and S on August 26 as the first Sony-published game on Microsoft’s console.

To celebrate Helldivers 2 becoming the first Sony-published game to hit Xbox consoles, the game looks set for a crossover with perhaps Xbox's greatest series.
