Halo Infinite Multiplayer is Free To Play
Halo Infinite Multiplayer has been made available as a free-to-play beta for those who have an Xbox One, Xbox Series S/X, and/or PC.
The beta includes access to season one with all the core maps and battle pass features.
It's good to note that all progress made in the multiplayer mode will also carry over to launch day on December 8th, so it won't be wasted practice. The first season will run until May 2022.
It's also good to note that Halo Infinite launches in December, and initially won't have a cooperative campaign function or Forge mode. According to official timelines, co-op campaign will come in the game’s second season, while Forge is planned for the third.
