Forest Guardians

Forest Guardians is a Tower Defense RPG game with 27 unique levels. As you advance, enemies in this game don't simply run through the level. They may team up to heal one another, increase speed during attacks, spawn helpers, transform, or even selfishly steal the health of their allies. Likewise building your tower is just the start of setting up your defense. Each tower can be augmented indefinitely with seven different ECOs (Essence Combined Orbs), each of which has it's own special abilities. If towers aren't enough, faeries are also there to help you along. And there is a detailed path upgrade system for elevating each “guardian” to tower defense domination. It's a whole new tower defense.
