Z Games, developers of Bubble Burst, is offering Pandemic over at the Windows Phone 7 Marketplace. As described by the developer, Pandemic has swarms of cute little viruses are invading your world and your objective is to stop them.
Pandemic is a colorful puzzle game where you have to match three or more viruses in a vertical, horizontal or diagonal line. Viruses can be moved freely around the board to create these combinations as long as the path is clear (they can't jump other viruses). The Bejeweled-like game has two different game modes, Pandemic and Zen. Pandemic Mode is a fast paced game that has your racing the clock while the Zen is a more relaxed, no pressure game.
To help you along the way there are a few bonus items (bombs and rainbow viruses) that will help you destroy more viruses. The game includes online leaderboards and a lengthy glossary defining each virus, covering the virus's gender, likes, dislikes and general description.
After playing Pandemic for a short period, I found it to be an entertaining, mildly addictive game. Graphics are nice and the game ran smoothly.
Pandemic is a free game and is available here (opens Zune) over at the Marketplace.
