Double Sequence: The Q-Virus Invasion

Double Sequence: The Q-Virus Invasion is a Nintendo DS puzzle game set against a universe-wide Q-Virus outbreak. Players shift and slide blocks of randomly arranged genetic code to connect matching colors and decode each virus strand.

The game features more than 30 planets, each presenting increasingly difficult patterns. The Nintendo DS stylus is used to move blocks between the two screens and create links, while progress tracking records personal-best move counts. Players can also create custom Q-Virus strands and share them with friends through Nintendo DS Wi-Fi.
