About Mark One

Mark One is a sci-fi twin-stick shooter in which you play a highly trained AI agent tasked with disposing of robots that have turned against humanity. Humans built robots to perform tedious tasks, but after artificial intelligence peaked, some robots went rogue and ignored the failsafe switch in their systems.

Fight the robots

The gameplay encourages you to face multiple enemies at once. You can use unlimited grenades to hit several enemies, replenishing ammunition for your equipped weapons with each hit. When your health is low, sonic punch lets you take health from enemies you hit.

Levels and enemies

The game has six levels with varying objectives, three boss fights, several kinds of robots to fight and a range of weapons. You can also use sonic punch, a devastating skill.
