BATTLE Mode

BATTLE Mode is a permanent vision in the floor selector, released on September 12, 2025, with a global queue since February 17, 2026. The wiki describes it as the successor to RANKED MODE, the April Fools 2025 mode, and says it runs on the current version of the game.

A match lasts about 250 rooms. Those rooms are a mix from The Hotel, The Mines, The Backdoor and The Outdoors, and rarely from Retro and The Rooms. Because the layout mixes floors, a single match can move between very different room styles. Entity pages that name BATTLE MODE among their modes are Blitz and Lookman from The Backdoor, which are two of the entities you can run into there.

Sudden death

At the 7 minute mark, sudden death begins: the maximum health of each player drops to 5, according to the wiki. That changes the math on every threat. Damage values that were survivable in a normal run, such as Lookman's 20, become fatal when your ceiling is 5, so the final stretch of a match is about avoiding hits entirely rather than absorbing them.

The practical lesson is to use the first seven minutes to build your position, since after that point the whole match plays under a much tighter margin for everyone in it.
