Hexagon Planet TD is a tower defense game that is played on a map of hexagons. Place towers on these hexagons to prevent the creeps from advancing to the portal without completely blocking their path. Upgrade your towers to increase their rate of fire, range, and damage. Ground enemies will follow the path created by your towers, but air enemies fly straight towards the portal. You also have special abilities, which you can use when fully charged. Don't forget to spend your stars on skill upgrades between missions!
