The premise
Humanity is on the brink of extinction. As the last surviving human, you wake on an Earth that has been invaded and infected by a foreign species of colonizer aliens. The surface offers no natural resources — only unforgiving slot machines and bio-mutants haunting every biome. Search the map for loot, drink milk from rusty spigots to fight hunger, fight enemies you'd rather not look at, power up mysterious pillars planted by an unknown group, and try to overcome the impossible: escape.
"After an alien invasion of planet Earth, the planet is left in a dangerous state with many bio-mutants haunting the planet. With you as the last remaining human, you search the map looking for weapons and armor. You fight bio-mutants and collect Aura to upgrade your bunker and possibly escape."
