Every human own billons of nanoscopic cells.
Some of these cells are doomed to protect our organism and fight foreign organisms. Use your cell colones to slowly progress and take over the map.
Instead of building towers and defending against hordes of monsters, play the opposite as an evil mage that builds his army from the ground up to dominate the lands.
