With the fate of the galaxy in the balance, it's your job to stop an enemy invasion before it's too late. Take control of things via one of four cyborgs, each a product of The Associated Network of Galaxies (known as TANG). All of the action unfolds over the course of 100-plus levels, utilizing more than 20 backgrounds to keep things visually appealing. Intense strategy and addicting gameplay pair up to create a handheld game that's nearly impossible to put down.
