Overview
Sneakers is a fixed shooter video game for the Apple II written by Mark Turmell and published by Sirius Software in 1981. An Atari 8-bit family version was released the same year. Sneakers was Turmell's first published game. He later was the lead designer and programmer of 1993's NBA Jam.
Gameplay
The player uses either the paddles or the keyboard to move a ship left or right across the bottom of the screen while shooting or evading enemies. If an enemy destroys the ship, a much larger mothership will descend and put a new one into play. The player begins with four ships in reserve and receives an additional one for each level completed. There are eight kinds of enemy the player must face, each of which attacks in a wave of its own with a unique strategy. After completing all eight waves, play proceeds to the next level in which the same enemies attack again, but in greater numbers or more challenging ways.
