Boss Stem Cells open routes and raise the stakes
Activate the required number of Boss Stem Cells for a run to access gated doors and routes; higher difficulty also increases enemy challenge and cell drops.
Dead Cells remains a complete released roguelite; its creators ended new creative content with Update 35. Persistent cells unlock gear at the Collector, while Boss Stem Cells raise difficulty and open new branches. Use Hunter’s Grenade to force a missing enemy blueprint, or Boss Rush for a contained boss-and-cell run.
