Game of the Day: Desktop Tower Defense Pro
Winning in a tower defense game involves fending off waves of attackers by building weapon stations and upgrading them accordingly. In PopCap's game, your enemies are zombies and the plants are your weapons. In DTD, your enemies are little blobs marching on your desk and your weapons are various types of gun turrets. I recommend that beginners play through the first 5 levels in Scenario mode to get up to speed. Plus, there's plenty of other modes for experienced players to tinker with, such as Sandbox (design your own level), Sprint (race-against-the-clock), and Multiplayer.
