About Biomass

Biomass is an adventure set in a sinking city where a perpetual flood separates three towers that hold most of humanity. An eternal lighthouse looms above them as a primordial process repeats. You explore the interconnected world, encounter factions with their own agendas and travel toward the lighthouse’s heart. Your actions and choices affect the events in different areas and the possible outcomes for the city’s inhabitants.

Explore the sinking city

You use your wits to find different ways to cross the city and gather weapons and resources to overcome obstacles along the way. The world’s history is mysterious to newcomers, but exploring its lore can reveal its secrets.

Fight your way forward

Combat supports a range of approaches. You can switch between melee weapons during a combo, use beam weapons to parry or deflect other beam weapons, or focus on firearms as a gunslinger. Different playstyles can suit different situations, and the world contains a wide range of foes that demand varied skills.

Boss fights have dynamic phases: each boss has a hidden phase that you can trigger or skip by meeting certain requirements.
