Out of all the games I looked at this week, I definitely poured the most time into Plague Inc. This single-player strategy title puts you as the guiding force behind a globe-spanning disease, including its means of transmission, its symptoms, and its spread from region to region.
Catapult King by Wicked Witch Software launched onto iOS today, offering Angry Birds-style destruction with 3D models and a medieval twist. Your goal is to knock down castles that stand between you and a princess that has been captured by a dragon. You change lateral angle, elevation, and force of the catapult, and can get a bit of extra guidance thanks to magic potions that you earn over the course of gameplay or through in-app purchases.
