Coming 2026 on Steam, on PC and in VR
A co-op roguelike FPS with waves of monsters, boss fights and procedurally generated levels.
Somewhere in the desert
Something waits under the sand.
In the middle of the desert stands a structure that no map records. Its door opens onto a cavern, and the cavern onto a whole world under the earth, full of creatures.
Many who went down never came back. The few who did speak of an ancient civilization, deeper still.
Underworld in brief
- 01 A co-op roguelike FPS Go down with your team, or alone. When a run ends, the next one starts from the top.
- 02 PC and VR, same match Play on a screen or in a headset, together.
- 03 A new descent every run Procedural levels, waves of monsters and a boss at the bottom of each layer.
- 04 Coming 2026 on Steam Wishlist it and Steam tells you the day it comes out.
You
The Hunter
One of the few brave enough to go down.
- 01
The expedition
He crossed the dunes with the expedition truck. From the door of the structure, the only way left is down.
- 02
The sword
Slung across his back, always within reach. Down there, bullets run out; the blade does not.
- 03
What he carries
Kills pay for weapons, perks and upgrades on the way down. When the run ends, only the Undercoins he banked come back with him.
- 04
Your hands, your eyes
Play him on a screen or in a VR headset: the same moves, in the same match.
Layer after layer
Hold the line.
Monsters come in waves, each one harder than the last, with special waves to break the rhythm.
Every layer of the Underworld has its own enemies, its own environment, its own story and its own boss. Your team chooses the route down.
- A few of them, slow. Learn the room.
- Each wave harder than the last.
- Then special waves, to break the rhythm.
Every kill pays.
Kills earn points, and every point is a choice.
- Open doors to reach new rooms
- Buy perks and stack the buffs
- Buy weapons and upgrade your gear
- Try the Mystery Box if you feel lucky
- Bank Undercoins the currency you keep between runs
The mimic
Not every chest is loot.
One of them sits still, lid shut, and waits.
- 01
A chest like any other
Wood, iron bands, a brass lock. Nothing moves.
- 02
It wakes
The box rattles. Two yellow eyes open, one after the other. Then the lid bursts open on teeth and a long tongue.
- 03
It bites
It rears back on its hind feet, lunges and snaps its lid shut. Then it shakes, jaws clamped, before it lets go.
No two descents alike.
Levels are built from hand-made rooms and random rules. The paths, the fights and the rewards change with every run, so the way down is never the same twice.
The bottom of the layer
Every layer has a keeper.
Learn how it fights, then bring it down together.
- 01
The Riftkeeper
It waits, curled up, at the bottom of its layer. Come close enough and it wakes.
- 02
Learn how it fights
Every keeper has its own attacks. Watch them, then answer them.
- 03
Bring it down together
Beat it as a team and the way to the next layer opens.
Between runs, the Tavern.
This is where the team regroups. Talk to its regulars, then spend your Undercoins on new weapons, perk levels, starting kits and boosts before the next descent.
PC and VR, same match.
Play on your PC screen or in a VR headset: either way, you descend together in online co-op. Or alone, if you dare.
The trailer
One minute in the Underworld. Sound on.
