Shelter 78: Mutant Protocol

The world above is gone.
Radiation, hunger, and mutation have taken everything.
Now, buried deep underground, humanity’s survival depends on you.

You are the checkpoint officer of Shelter 78 — the last barrier between safety and chaos. Every survivor who approaches your gate could be humanity’s hope… or its downfall.

LOOK CLOSER
Scan each survivor for signs of mutation — strange skin, abnormal breathing, or glowing veins. Use thermometers, UV lamps, and breathing analyzers to uncover what lies beneath the surface.

MAKE THE CALL
Let them in, isolate them, or… eliminate the risk. Every decision shapes the future of the shelter — and the fate of those who trusted you.

MANAGE THE BUNKER
Inside, survival is a daily battle. Distribute food, medicine, and fuel wisely. Keep the power running, upgrade critical systems, and maintain order before panic takes over.

FIGHT THE MUTATION
Some can still be saved. Heal mild infections, develop treatments, and preserve your dwindling population — but beware, not all mutations stay dormant for long.

REINFORCE & UPGRADE
Expand your isolation chambers, improve medical labs, and strengthen defenses against what lurks beyond the gates.

CHOOSE WHO LIVES. WHO DIES. WHO CHANGES.
Every heartbeat, every scan, every decision — it all leads to one outcome: survival or extinction.

CROSS-SAVE
Start on PlayStation®4, continue on PlayStation®5 — your progress travels with you.

Keep the infection out.
Keep humanity alive.
You are the checkpoint.
