Each run is a fight against time, toxins, and the collapsing world around you.
Loot fast. Push deep. Make it back alive.
The city is a graveyard of steel and concrete, swallowed by decades of collapse. Streets once crowded with life are now choked with rubble, abandoned machinery, and the silence of what was lost. Danger lives in every shadow, and nothing out there is on your side.
Invisible at first, the toxic contamination spreads fast. Zones collapse inward — what was safe moments ago becomes lethal in seconds. The longer you stay in the open, the more the world tries to kill you. You can't fight the toxin. You can only outrun it.
It's the only constant in a world without rules: the shelter. Fortified, warm, alive. Your base. Your lifeline. Every run begins and ends there — if you're lucky enough to make it back. Each successful extraction makes it stronger, and makes you harder to kill next time.
The clock starts the moment the shelter doors open. Every second you spend outside is a second closer to catastrophe — loot smart, move fast, and don't get greedy.
The toxic boundary doesn't wait. It closes in relentlessly, shrinking the safe area and forcing you deeper into risk — or forcing a desperate sprint back to safety.
What you carry back matters. Resources upgrade the shelter. Weapons and armor tip the odds in the final encounter. Every item is a calculated risk worth taking — or leaving behind.
Just when you think you're home safe, the game hits back. A final threat — elite enemies, a guarding mini-boss — stands between you and extraction. Win or die trying.
Fluid, responsive controls built for mobile. Dodge, aim, strike — survive through skill, not chance. Combat rewards patience and aggression in equal measure.
Toxic fog rolls through desolate streets. Embers drift past crumbling towers. Every environment is crafted to feel both beautiful and lethal — a world that breathes dread.
The run begins in safety. Gear up, review what you've got, and choose your route. The shelter door won't stay open forever — make every second of prep count.
The doors open and the clock starts. Scavenge the ruins for gear, supplies, and upgrades. The deeper you push into the city, the better the loot — and the deadlier the cost.
The toxic boundary begins closing in. What was safe is now lethal. The zone shrinks relentlessly — pushing you inward, cutting off escape routes, raising the stakes with every second you delay.
Sprint. Fight. Survive. The route back is no longer safe — enemies close in, the environment turns hostile, and the toxic fog bites at your heels. There is no second chance if you fall here.
The shelter door is in sight — but something stands in the way. Defeat the final threat, breach the entrance, and lock the doors behind you. Victory belongs to those who survive to the end.
