Microsoft has confirmed that Halo 3 will be coming to PC on July 14th and will be part of the Xbox Game Pass for PC, and as part of the Halo: The Master Chief Collection. This will make it the first time that the final part of the first trilogy will be available on PC, as the original 2007 version was released exclusively for Xbox 360. This won’t be the last Halo game jumping to PC with Halo 3: ODST and Halo 4 both slated to be released at some point in the future.
343 Industries is continuing further with Halo franchise, with Halo Infinite coming. Halo Infinite was announced back at E3 2018, before being confirmed at E3 2019 to be an Xbox Series X (then codenamed Project Scarlett) launch title and cross-generational release, and also coming to PC. The game is built in a new Slipspace engine, created specifically for the title. It will also feature split-screen co-op once more.
Recent rumours have suggested that the game will be a “one shot” story, similar to the 2018 God of War. That is to say that it will be one continuous experience with no cuts or breaks. That would be a fascinating choice in its own right, but so too is the decision to feature the Banished. These were the antagonists found in RTS spin-off sequel Halo Wars 2, led by the banished Brute warlord Atriox. It seems to suggest that Atriox has died, but that his followers continue to fight, taking the battle to a new ring.
