About this game
Soldier.
If you are reading this message, it means you have been selected for deployment. The planet Keller has fallen into chaos: alien lifeforms once classified as harmless have mutated into relentless killing machines. Entire expeditions have vanished, entire battalions… erased.
The BFA does not ask for heroes: we create them!
You will be dropped into hostile territory with one objective: destroy every threat. Advance, adapt, survive: this is our motto! But be prepared: the enemy is countless, the terrain is unstable and death is not a possibility, it is an expectation. But for every creature you exterminate, every abomination you destroy, and every second you remain alive... you will bring Keller one step closer to liberation. Before BFA domination, of course.
This is why we choose you: you are not just a soldier, you are the will of the BFA made flesh! And should the horrors of Keller attempt to break you… should the darkness attempt to claim you… then let it learn what fear truly means!
For the BFA. For humanity.
For victory!
Transform between a human soldier and a demonic entity as you carve your way through hostile alien hellscapes. Two Sides of Hell delivers intense twin-stick action where mastering both forms is not just an advantage: it is the key to survival.
Switch seamlessly between precision gunplay and brutal demonic combat, adapting your strategy against relentless hordes of extraterrestrial abominations, deadly environments, and unpredictable boss encounters.
Built as a breath of fresh air from conventional modern controls, the game embraces original twin-stick, no-mouse-required gameplay, returning to the pure, skill-driven roots of arcade action while layering it with modern roguelite depth.
Every run drops you into procedurally generated alien hellscapes where weapons, upgrades, and survival itself are never guaranteed.
BE THE SOLDIER
Step into the boots of a BFA operative and fight with precision, mobility, and overwhelming firepower. Run and jump as you tear through hostile alien environments packed with relentless enemies and lethal hazards.
Discover and equip powerful weapons, manage your ammunition, and adapt your loadout on the fly while procedurally generated levels constantly reshape each run. Skill, reflexes, and tactical awareness are your greatest assets.
BECOME THE DEMON
Defeating powerful abominations triggers a brutal transformation. Stripped of your weapons, your humanity fades while you become the very horror you fight against.
Combat shifts into a ferocious wave-based melee experience fuelled by rage. Crush enemies with demonic abilities inspired by fallen bosses, survive escalating assaults, and confront the ultimate test of your corrupted power.
FIGHT TOGETHER
Jump into cooperative combat and face the alien threat together. Coordinate your movement, combine your firepower, and cover each other while fighting through levels filled with enemies, hazards, and boss encounters.
Co-op changes the flow of every run, forcing players to manage space, resources, and enemy pressure together. Whether you are fighting as soldiers or surviving the chaos of demonic combat, teamwork becomes another tool for survival.
DEATH IS ONLY THE BEGINNING
Keller is unforgiving and death is inevitable, but every failed run makes you stronger.
Collect valuable resources, unlock permanent upgrades, and enhance your capabilities back at the Hangar. Expand your arsenal, improve your survivability, and experiment with powerful Power Plates that reshape your playstyle: from mobility boosts and defensive shields to devastating offensive enhancements.
Every run throws you into procedurally generated combat scenarios where weapons, enemy compositions, environmental hazards, and boss encounters constantly change, forcing you to adapt your tactics on the fly. Once you fall in battle, you must analyse, adapt, and evolve before returning to the battlefield.
Because in Two Sides of Hell, defeat is never the end: it’s progression.
