Boss Floors

Boss Floor Types

Boss floors replace standard Atlas layouts with arenas tied to specific entities. They alter tasks, timers, and rules. Envy’s Coliseum (Floor 20 standard) uses thirteen information papers. Sloth’s Cathedral runs timed all-task completion after first task with no code keypads. The Mall hosts Mannequins with high task counts in tight retail construction.

Big Bad upgrade can force boss detours without advancing floor count—useful for practice or Bestiary farming when chosen intentionally.

Envy’s Coliseum

Grey coliseum snow arena with stone walls, faceless clipboard corpses, and Leeching Rose traps growing over time. Envy visible most of the time due to lighting and arena size. Papers sit at fixed locations across all encounters—learn routes from repeated runs or our Envy guide.

Sloth’s Cathedral

Large cathedral with pillars, long tables, and many tasks. Sloth sees through pillars but not walls. Four-minute thirty-second timer after first task; blackouts accelerate Sloth. Timer expiry triggers unlimited hearing on movement.

The Mall

Huge plus-shaped under-construction mall mixing live and fake mannequins. Power flickers reposition mannequins. Recommended five-plus teams with dedicated watchers. Sector 3C Biological Research Wing lore hints at containment origin.
