Ghost Recon Breakpoint is getting a new Immersive mode in its next update. Immersive mode limits your health regeneration, resources, and HUD, and eliminates the tiered loot system. You'll customize the same on or two primary firearms throughout your journey, unless you loot new weapons from fallen enemies.
Immersive mode is one of three ways to play through the game via the Ghost Experience, Ubisoft's official title for the new update. Another way to play is Regular mode, which is the Breakpoint you're used to. Finally, Custom mode lets you tweak a series of rules including injury risk from enemy bullets, number of bandages you can carry, and availability of Maria's Shop. These are detailed in the video above.
