Blockbuster, also known as Impact in Europe, is a Break Out clone.

The user controls a paddle and needs to catch a ball with the paddle each time it comes down. When the ball hits a brick, it is destroyed (unless it's made indestructible). Sometimes, a bonus will come out of the brick. This adds to the 'bonus score'. When the player collected one or more bonuses, they may 'release' them, and they receives a powerup. Each 'bonus score' has a different powerup: the most powerful powerups need the largest number of bonus points. Impact comes with a lot of levels and a level editor.
