Fresh off the release of Halo 3 earlier this month, FPS games as part of a package of other updates.
In the latest space games in 2020. Among them are cross-play, input-based matchmaking, sever region selection, and mouse-and-keyboard for Xbox. Those first three will come in a package at some point, while the fourth will be part of another roll-out.
Mod is still coming, the post says, but there's no release window as yet. The EULA – the rules and legal agreement for community-generated content – is in its final stage of iteration, and once that's done, a date can be organised. Halo 4, and Halo 3: ODST's campaign and firefight, are coming to PC this year, too, and firefight will have updated networking.
Speaking of ODST, Bungie's Halo spinoff is getting a test flight soon, and some of the features are listed. Several missions, multiplayer maps, and playlists will be playable, and accessibility options for subtitles, change language, text-to-speech, and speech-to-text will be available.
Halo 3 came to Halo: The Master Chief Collection in July, and Infinite's multiplayer will be free-to-play.
