Protect your gems from being stolen by â€œgoodâ€ heroes in this tower defense game. Overlord, you have all the power of orcs, undead and demons.
Use mouse (hold SHIFT to build multiple towers or cast multiple spells). The game has a built-in tutorial. Try to annihilate the enemies before they grab a gem, but even if they do, youâ€™ll have a chance to annihilate them on their way back and youâ€™ll save the gem.
