Some of Halo Infinite’s most important features won’t be available on day one.

In a lengthy development update video released on Friday, Halo Infinite developer 343 Industries talked over the feedback from its recent multiplayer tech test and also dropped some news about the upcoming launch, covering what is and what isn’t going to be in the game on day one. The launch day will not see some Halo essentials like campaign co-op or the Forge mode.

Campaign co-op will be available for Halo Infinite Season 2. Each of the multiplayer seasons lasts around three months. Joseph Staten, creative director, says that “Unfortunately” we had to make the difficult decision of delaying shipping campaign co-op in order to provide a high quality launch experience.
