Frost Nova

Hold the line in Frost Nova, a lane-defense game where snowball invaders roll down five icy lanes toward your frost crystal. Drag frost towers into the lanes and they will fire freeze bolts on their own: the first hit freezes an enemy solid, and the second hit shatters it into glittering ice.

Face a growing bestiary of foes. Fast runners race ahead, armored brutes soak up damage, healers mend their allies mid-roll, and flyers dart across the field. Every fifth level ends with a massive boss yeti stomping toward your crystal.
