ZERO PROTOCOL Free Download (v1.0)

Game Overview

Uncover the secrets of the IAS Antarctic Research Complex and fight for your survival in this immersive first-person sci-fi thriller.

Focus on Exploring: Choose passwords for doors, search for access cards to terminals, repair damaged equipment and combine items. Think with your head, this game will not lead you by the hand!
Intense battles: You have a gun, but that doesn’t mean you’re safe. The enemies here are deadly, and not all of them can be killed…
The atmosphere of cold loneliness: Graphics inspired by classic 3D games such as Zero Tolerance, System Shock and Half Life, combined with atmospheric sound effects, make the game world even darker and more inhospitable.
Nonlinear and Multiple Endings: Balance between clarity and madness, make conscious or unconscious decisions and find out where they lead!
