No backup.

Somewhere below the surface of a dead world, an ISS survey crew went silent. Their distress beacon is still pinging.

You're going after them in an emergency pod that was never built for this. Its weapons have been revoked, the autopilot is compromised, and the only thing between you and the rock is a few shields and your own hands on the thrusters.

Follow the outposts they left behind. Bring them home.

Descend

Dive deep into a hostile alien world. Follow the path of outposts laid down by your missing crew. Navigate dark tunnels, toxic rivers, unstable machinery and erupting lava lakes in a desperate push toward the planet’s core.

Adapt

Choose your ship’s core before each mission to match the threat ahead. Tighter control, stronger shielding or zero gravity: each one is a different way to survive. Master them all to conquer the planet’s ever-shifting challenges.

Parts bay

Pick your core

- Shields Core -

Shields
3 Standard
Mobility
Steady

A regulation ISS scout core. The shields can each withstand a single impact. However, they fail in extreme heat.

- Omni-Thruster Core -

Shields
1 Standard
Mobility
Agile

A prototype ISS core fitted with omni-directional thrusters. The standard shield can withstand a single impact.

- Hyper Shield Core -

Shields
1 Hyper
Mobility
Steady

An experimental ISS core with an advanced shielding system. This single shield can protect against extreme impacts and heat.

- Anti-Gravity Core -

Shields
1 Standard
Mobility
Precise

A modified ISS core equipped with anti-gravity technology. The standard shield can withstand a single impact.

- Hard Core -

Shields
None
Mobility
Steady

A fragile core for experienced pilots only. No shielding systems installed. Careful landings required.

Survive

Your emergency pod is not equipped to fight. The craft is fragile and exposed, with no defenses beyond a few shields and your own skill. Avoid deadly hazards, environmental traps, corrupted machines, and the strange forces that seem to anticipate your every move.

Every zone ends on a landing pad, and you’d better touch down upright.
