About This Game

🌍 Year 2155 — The World After the Fall

After the nuclear war, Earth lies in ruins.
Toxic leaks and radioactive storms have turned entire regions into forbidden wastelands.
Among the survivors, many have mutated — losing their sanity, their humanity… and becoming something else.

🧬Humanity’s Last Line of Defense

Only a few safe zones remain across three continents.
You are a member of the Mutant Detection Unit (M.D.U.), humanity’s final safeguard.
Your duty: inspect every entrant from the contaminated zones —
verify their identity, observe their behavior, and decide who may pass.

🔎Attention to Detail Means Survival

Every day, new faces arrive — desperate, wounded, terrified.
But one wrong call could unleash a monster inside the walls.
Scrutinize every clue. Spot the inconsistencies.
Because in this world, a single mistake can doom an entire colony.

⚠️One Job. Infinite Consequences.

It’s not just about who enters —
It’s about who you trust.
Your judgment defines humanity’s future.

🧠Do You Have What It Takes?

Join the Mutant Detection Unit and help protect the last bastions of civilization.
The fate of mankind rests in your hands.
