About this game
A ROBOT POWERED BY THE HUMAN HEART
A robot, known as 339, is trapped in the depths of his mind, waiting to be rescued. A green robot, who does not reveal his identity, awakens 339 and explains to it who he is, where it is, and what he must do to escape. The zombie robots and robot soldiers it encounters on this adventure, meanwhile, lie in wait to clash with 339 as the main threat.
PORTALS THAT PLAY A ROLE IN SOLVING THE LEVEL
Portal doors within the level are used to overcome dead ends. These portals, which open to another location, play an important role in progressing through the level.
INFINITE ARCHITECTURE WITH A BLUE ATMOSPHERE
The ‘Dejavu’ section, with its infinite architecture and blue atmosphere, is a vast section that you must navigate by finding a way up, defeating the enemies you encounter and climbing your way through. To create a path, you must move the metal blocks around you, find a route through the water and press on. You must use the hook you carry at your waist, sometimes to slide down a rope and sometimes to latch onto a pole to swing from.
As you draw power from the human heart, you must nourish your heart with blood vials when your health is low. You must fight your way out of this vast environment, which is teeming with six different types of enemies: normal, invisible, armoured, and their virus-infected zombie variants. This adventure awaits you.
