Defend Your Honor! [9.067] Votes: 15
The king has offered command of his vast army to the Man (or Elf) who returns his missing Golden Statue. It's up to you to find it and win this grand prize, and maybe make some friends on the way. A mixup of the Tower Defence with a dash of strategy. I wanted to create a tower defence game that didn't become stagnant, so each battle is short and sweet, and feels like a smaller part of the grande scheme of things, rather than wave after wave of repitition. The strategic placement of units is the key to victory!
