Lunar Workshop has just released the Campaign Update for their artillery/strategy game, Digitanks.

Your computer has been infected. All manner of Bugs, Viruses, Worms, and perhaps even some Snakes have taken root in the digital landscapes of your PC. It’s up to you and your fleet of Digitanks to clear them out. Build tanks, compete for resources, and expand your base while clearing the infestation from your hard drives.

The Campaign Update features two new missions, a new Firewall that allows you to automatically defend your base, and an improved interface. Digitanks is also now available for whatever you want to pay through the end of October (one dollar minimum please).
