Two Sides of Hell

Two Sides of Hell is a twin-stick action game set on Keller, a planet overrun by alien lifeforms that have mutated into killing machines. You play as a BFA operative, fighting through procedurally generated alien environments and switching between human soldier and demonic forms. The BFA’s objective is to destroy the threats and bring Keller closer to liberation under its control.

Fight as a soldier

As a soldier, you run and jump through hostile environments, using precision gunplay and firepower against relentless enemies and lethal hazards. You discover and equip weapons, manage ammunition and adjust your loadout as levels reshape each run. Weapons, upgrades and even survival are not guaranteed, so you must adapt with skill, reflexes and tactical awareness.

Become a demon

Defeating powerful abominations triggers a transformation that strips away your weapons and humanity. Combat becomes a wave-based melee fight fuelled by rage: you crush enemies with demonic abilities inspired by fallen bosses and face escalating assaults that test your corrupted power.

Co-op combat

Local co-op lets you fight alongside a friend. You coordinate movement, combine firepower and cover each other through levels filled with enemies, hazards and boss encounters. Playing together changes the flow of each run, requiring you to manage space, resources and enemy pressure as soldiers or during demonic combat.

Runs and progression

Each run takes you through procedurally generated combat scenarios where weapons, enemy compositions, hazards and boss encounters change. Death is inevitable, but you can collect resources and return to the Hangar to unlock permanent upgrades, expand your arsenal and improve your survivability. Power Plates offer enhancements such as mobility boosts, defensive shields and offensive upgrades that can reshape your playstyle.

Game modes and content

The game includes Endless and Multiplayer modes with leaderboards, as well as multiple endings that reveal the truth behind Keller’s nightmare through divergent story outcomes. Its content includes 20+ enemy types, from alien creatures to bosses, and 70+ tools of destruction, including weapons, upgrades and abilities.
