About Proto Zero

Proto Zero is a 3D action game set in the far future, inside an automated megastructure inhabited by hostile enemies called AUTOs. You play as YUUTO, who wakes from a cyber container that has kept him alive for an unknown length of time. With only the name on the container to identify him, he fights through hordes of AUTOs and tries to escape the megastructure to discover the origins of this world.

Combat systems

The game’s dynamic difficulty rises as you perform better. Higher severity brings better rewards from power moves. Power Protocols let you use moves to power up, move faster, heal or pollute the environment with Proton. The Free Form Ligament system lets you chain any limbs together or hold each limb for stronger attacks. You also gain Combat Prowess by performing certain actions, improving your performance and boosting your energy and health.

Game modes

  • Culling Time: survive against timed enemy hordes in the CYBUNKER, taking out as many as possible before the timer reaches zero.
  • Liquidation Station: fight without a time limit, defeat a designated number of enemies and aim for the best time.
  • One Chance Clear: play the main story with permadeath; dying resets the game from the beginning.

Visual style

Flat Futurism combines a flat, cel-shaded aesthetic with complex mechanical geometry.
