Celestial Defense

By the year 2185, deep space exploration and asteroid colonization had been successfully achieved by humans. However, this progress was threatened by the looming danger of an alien invasion. While extracting resources and energy was one challenge, defending against invaders was another. Your mission is to safeguard the main power core from intruders, utilizing teleports and towers at your disposal. Failure to protect the core will result in defeat. Use your resources wisely to defend your territory. Unfortunately, strategic options are limited and towers can only be built in specific locations. With 25 levels, 30 towers, and fast-paced gameplay, you must face 7 different types of enemies. Compete against other players on the OpenFeint rating system.
