Send a horde. Hold the line.
Tower defense where your rivals send the waves, and you send yours back.

Every creep is a weapon.
Buy creeps and send them at a rival. Every one you send raises your income for the rest of the match.

Your towers are the maze.
Build anywhere on your side. The creeps walk the road you make.

Last keep standing.
Two or three players online. Leak too many and your keep falls.

Towers that grow with you.
Start in wood. Rank up into stone, ice, fire and lightning.
