The Lost Planet Tower Defense

Far from any settled route, a deserted world sits under threat again after earlier invasions drove away both its residents and the alien attackers. New construction rose around a central stronghold, and city building had already begun when another assault hit in The Lost Planet Tower Defense. The planet's defense now rests with the chief strategist guarding that main tower and the growing settlements around it.

How to play?

At the first offensive zone, place defense towers charged with fire or lasers before the opening enemy wave reaches the building. Fallen aliens drop crystals. Pick them up to refill energy and place more defenses where the route needs extra damage. During the battle, sell any tower that no longer fits the route. Move it to a better spot and block the next push before enemies break through.
