Crystal Defenders is a defense-based strategy game where players protect a path using units inspired by the job classes from Final Fantasy, including Soldiers, Archers, and Black Mages. Each enemy that makes it through the entire route results in the loss of a crystal for the team. The game features three modes: W1 serves as a tutorial to teach the fundamentals, W2 adds Power Crystals to deepen the strategic elements, and W3 offers more intricate and challenging maps.
