Gameplay

Every time you die, your body is recreated through cloning, but that's only half the story.

Your memories are just as important. They are stored as data on a chip, drilled deep into your brain.

Without a chip, you’re a hollow shell; an empty meat suit, lifeless and mindless.

And once they run out, you get the BAD ENDING.

The only way to reclaim brain chips is to find injectors capable of penetrating the skull and extracting a chip from your dead body. Isn’t the cycle of life marvelous?

But be careful - everything comes at a price…

Save at the comfort of your safe room, or the game will save for you when you die.

But Remember: you have a limited amount of lives!

Carry items in your inventory or store them in the convenience of your safe room.

If you die, you can retrieve your items from your dead body - no time limits, no penalties. But remember: every death brings you closer to game over.
