About Prototype-Cube

Prototype-Cube is a high-difficulty 3D action shooting game set in a buggy chess world. You use a sword and bullets to fight out-of-control chess pieces while dodging attacks, traps and stage hazards. Each stage has a Warm-up Mode for practice before the main challenge.

Story

In a world not far from the present, researchers work to give robots consciousness. During a demonstration of their achievement using a chess game, the chess pieces go out of control and bugs spread through the chess world. You venture deep into that world to find the cause.

Fight through each stage

You battle enemies with your sword and bullets, evade their attacks and face a chess executive boss at the end of each stage. Each boss has its own attacks. Traps and other hazards make the stages dangerous as well as the enemies.

The Hot meter system scores your play in real time. You can aim to take no damage and defeat as many enemies at once as possible. Enemies and traps can damage your vision, audio or control modules; you can repair yourself quickly, without stopping time.

Plugins and customization

You can gain admin rights and unlock plugins that add features and offer new challenges. The admin password becomes available after you clear all stages.
