If you are into defence games and you are a proud owner of a Blackberry Playbook, then you should check out Slice 3 Fortress Defence. This Playbook app was released on the 5th of December by Aartform Games. What makes this app a good time-killer is that it provides you with 45 unique fighters, 40 levels of pure, non-stop combat along with the ability to generate strategies with 7 damage types to defeat your foes. Another great feature to the game would be the graphics. The characters are really cute and cuddly (in my opinion), but yet destructive. This Playbook app is $0.99, so this is a pretty small price to pay for a pretty cool game.
