BreakIn is a version of a classic pong-style game from the late 1970's. Move your paddle to hit the ball. Take out all the bricks and move to the next level. The game gets more difficult as the ball speeds up and your paddle gets shorter. A Java ME enabled device with CLDC 1.0 and MIDP 1.0 support is required. The version with sound requires a device with Sprint PCS extensions for MIDP 1.0.
