Halo 3 and ODST can now be played crossplay through the Master Chief Collection.

Developer 343 Industries released a new update to the eight year old game (or 15 for Halo 3 and 13 for ODST) that adds a number of new features.

Namely, players can now play the campaigns of Halo 3 and ODST cooperatively with other players whether they’re on Xbox One, Series, or PC.

Doing so may not work perfectly straight away, 343 Industries warned, as “the team requires additional insight from real players with different networking setups,” they said in a blog post.

The update adds several other features to the Master Chief Collection and weighs in at 21.56GB on Xbox, 26.5GB on the Xbox PC app, and 11.2GB on Steam.

A new mode called Flood Firefight has also been added to ODST, which essentially adds new enemies to the pre-existing Firefight mode.

The Flood enemies bring some spookiness to the mode with a fog that accompanies them into battle, and can now occupy vehicles, wield support weapons like turrets, and infect ODSTs and Elite Majors.

General performance upgrades and bug fixes were made across all games in the Master Chief Collection, and 343 Industries has promised it will continue to improve it in the future.

In our 9/10 review, IGN said: “Despite MP troubles, Halo: The Master Chief Collection’s classic campaigns are amazing examples of FPS done right.”
