A deadly virus is sweeping across the universe and the only way to stop it is by sequencing the DNA and cracking its genetic code. Double Sequence: The Q-Virus Invasion is a puzzle game, somewhat in the vein of a Rubik's Cube, in which players must arrange colored blocks in groups by moving them from one DS screen to the other. There are 30 different planets, each hosting a different configuration of the virus. Players can create their own puzzles and share them with friends using Nintendo's Wi-Fi Connection, and game progress is tracked so gamers can try to decrease the number of moves it takes to solve each puzzle. ~ All Game Guide
