Build towers and defend your base against the waves of blood-thirsty incoming zombies. Earn points to upgrade your existing towers or add more new towers.
The King has ordered the mighty heroes once again to bring more gems. Gather the evil forces, build towers, upgrades, cast the mighty spells, do whatever you can to not let them take your gems!
Use towers to build a labyrinth from entrance to exit. Each tower can be upgraded 4 times. With each wave, enemies will become stronger, so use money you earned to upgrade reasonably.
