Secret Halo Infinite multiplayer modes have been found by players - Windows Central

The Halo community on Reddit has discovered several hidden Halo Infinite multiplayer game modes by launching the game while disconnected from the internet.

The list of modes includes a collection of variations of the Arena, Fiesta, Ranked, and Tactical (SWAT) game types.

The specifics of each mode are fairly straightforward (for example, Tactical: Slayer Sidekicks means SWAT with the Sidekick pistol only), but some, such as the Attrition variants of Arena and Fiesta, are modes we don't know much about right now.

Overall, it's good to see that the developers have created more multiplayer modes for Halo Infinite, as many are currently frustrated with the game's lack of content.

Notably, 343 Industries is planning to add new Halo Infinite multiplayer playlists before 2022, including playlists for Fiesta, Tactical Slayer (SWAT), and Free-For-All.
