Defend with powerful towers that automatically form walls. Use unique traps. Build and command mobile ground units. Hit the enemy with a variety of strikes and fighter sorties.

Tower Defense with Mazing

Maze the Enemy

Defensive towers and barriers automatically generate a laser fence when constructed close together, allowing your mobile units passage while restricting enemy movement.

Defend Your Colony

No colony building is safe from attack. While protecting the Citadel is your primary objective, the enemy will not discriminate when it comes to attacking your colony.
