Mama's Sleeping Angels is a cooperative survival game set inside the dream of a goddess known as Mama, an eternally hungry entity who has trapped players within her subconscious during what should have been an ordinary sleepover. Dragged into the depths of this dreamscape, up to four players must explore procedurally generated dreamworlds, fight the creatures that inhabit them and gather cursed objects to offer as payment for their escape. The alternative to paying that price is straightforward: your life.

Six distinct dreamworld types shift their layouts with each run, populated by hostile life forms and scattered with cursed objects that carry bothersome powers. Players analyze these objects using a flip phone, a handheld tool for investigating the ethereal surroundings. Combat draws from an arsenal that ranges from sniper rifles to chainsaws, while powerful masks alter a player's abilities once equipped.

Between expeditions into the dreamworlds, the house serves as a safe zone. A computer room there catalogues everything encountered so far, from life forms to curses to items, building a growing record of each journey. Twelve NPCs lie dormant across the dreamworlds waiting to be found and woken up, expanding the circle of survivors pulled from Mama's grip.

Mama's Sleeping Angels is not yet available, with the game still in development ahead of its planned release. The central question it poses to players is a blunt one: gather enough cursed offerings to satisfy Mama, or become another of her sleeping angels.
