Duskers

Sci-fi setting

You guide a squad of drones through derelict spaceships using a command line, relying only on sensors and limited camera feeds. Its roguelike survival structure and oppressive atmosphere keep tension high.

Receiver

Challenging difficulty

A minimalist first-person shooter where every gun action is manual: ejecting the magazine, loading rounds one by one, cocking the hammer. Randomized levels and scattered tapes tell a dark story in fragments, while turrets and drones punish every mistake.

System Shock

Lots to discover

This remake of the cult classic leaves you alone on the Citadel space station, ruled by the deranged AI SHODAN. You explore sprawling interconnected levels, fight to survive, solve puzzles and piece together the story through audio logs in a bleak cyberpunk atmosphere.

Skyhill

Dark, serious atmosphere

You fight your way down a infected high-rise hotel floor by floor, juggling hunger, supplies and gear. A compact survival roguelike with a horror mood and constant resource pressure.

Noita

Challenging difficulty

Every pixel is physically simulated, letting you craft your own wands and chaotic spell combos to burn, flood or blow up the world. A brutal roguelite full of secrets where you often die to your own creativity.

Mosa Lina

Lots to discover

Mosa Lina is an offbeat, hostile take on the immersive sim where chaotic systems collide. You experiment your way through quirky puzzles and improvise solutions in an unpredictable world.

FTL: Faster Than Light

Sci-fi setting

You captain a starship on the run, rerouting power, directing crew and making tough calls in pausable real-time battles. Every run is procedurally generated, brutally tense and often ends in glorious failure.

Subterrain

Dark, serious atmosphere

A sci-fi survival game set in an underground Mars facility where you single-handedly manage resources, craft gear and fend off mutated creatures. Randomly generated levels and base upkeep create a tense, isolated atmosphere.
