"Why do people live?"

The world in 3230 is... well, you can barely call it a world by now.

There's a permanent post-post-post-apocaliptic winter. Humanity has destroyed itself after millenia of wars and destruction. they constantly focused more in building arms to kill eachother instead of, well, surviving. Cooperative. Human greed really knows no bounds, huh.

Whatever the case, whatever your reasons, you were traveling up the levels of this desolate city, probably in (vain) hopes of some sort of society up there still remaining, though all that remains are ruins of past generations.

Theres nothing left.

Humanity will go extinct after your generation fully dies off.

It will really be your Last Tour.
