In the BlackBerry Game Developer's interview we posted eariier this week, Nickel Buddy let us know they'd soon be introducing the first tower defense game for BlackBerry. Here it is! Field Towers for the BlackBerry Storm lets you control the field in an effort to stop the incoming waves of attacking enemies. You can grab it for $4.99 from the CrackBerry App Store. *Warning* Tower defense games can be highly addictive, so don't blame us if you spend all weekend playing it!
