MicroHexon Research has invented a transformative medical technology: autonomous nanotech machines that are no larger than a blood cell. When injected into the body they target and eliminate diseases at the cellular level. However, something has gone dangerously awry. The nanomachines have bonded to the diseased cells and are now multiplying inside the body at an exponential rate. Piloting a new prototype MicroBot, players must seek and destroy the infection before it consumes the human host from the inside.

In MicroBot, players battle malicious enemies as they travel through veins, bones, lungs and brain. The rhythms and fluids of the human body create a dynamic environment that affects movement and gameplay, providing both combat advantages and additional hazards to overcome. Just as each human body is unique, MicroBot dynamically creates new levels to ensure that the challenge is different every time gamers play.

As players eradicate the biotechnological infestation, they will harvest data fragments which allow them to unlock over 20 pieces of upgradable microtechnology. Using this newly acquired technology, players can strategically customize their MicroBot with powerful weapons, defensive systems, movement parts, and special abilities. With millions of possible configurations, players can build a MicroBot to suit any style of play.

Players can take on the infection together by teaming up in a cooperative drop-in/drop-out multiplayer experience. Not only will players battle side-by-side, but they can also upgrade their MicroBots simultaneously in the innovative co-op editor, where they work together to create the ultimate MicroBot team.
