Plot

This is based on the concept of the movie TENET by Cristopher Nolan.

You are a special forces soldier who must find all the pieces of a weapon that can reverse the entropy of the universe before SATOR, a very wealthy Russian tycoon who possesses the technology to travel through time by local control of entropy.

Gameplay

You have to solve puzzles in order to find all the pieces of the weapon.

To solve them you need to think smart before using the "Turnstile", a machine that can reverse the entropy of small objects and life forms so that you can harness your past self as a duplicate to combine your old actions with new ones, such as activating two levers at the same time.
