The same urge to snap a ruler in half or hurl a compass when facing the frustrations of high school geometry is channelled through geoDefense Swarm. This striking tower defence game takes a creative angle with open levels, but fails to measure up with flawed, often aggravating gameplay.
Destroying the geometric creeps that scurry across the screen is a matter of tactically plunking down towers. Unlike the first games that limited tower construction along set paths, geoDefense Swarm organises the screen into a grid of hexagonal tiles onto which towers can be placed. By devising intricate tower formations, you're able to direct the flow of enemies as they make a rush for the exit.
