Savage Moon is a classically styled "tower-defense" game in which players must protect a remote mining operation from waves of invading "Insectocytes." Gamers must tactically place different kinds of towers to handle the different speeds, sizes, and numbers of enemies advancing on the facility. As players advance, they can upgrade the size and firepower of existing towers, and obtain new towers and new technologies by redeeming credits earned on each level. The game features global online rankings of scores, so players can see how they stack up to gamers from all around the world. ~ Christopher Brown, All Game Guide
