Nanoblood is a scoring /scrolling game that takes place inside a blood vessel. The player is in control of a nano robot ship that has to survive to the different obstacles and diseases it will find on its path. The ship is pushed forward by the blood flow, at the rhythm of heart beats of the body he is inside. The player can push different keys to drive the ship. He has a special key to accelerate the heart beats and thus go significantly faster. If the heart rhythm is too high or too low, the ship will loose HP. The game can be played either as a single-player game or as a coop game. When playing in coop, a turret placed on the top of the nano robot can be controlled by the second player.
