Quadrun

The object of Quadrun is to destroy enemies ("captors") and rescue friendly characters ("runts") who are attempting to escape from the arena's central building. The player character is invincible, but has only a limited supply of their weapon, an energy ball that destroys the enemies on contact.

The game is a series of waves of enemy characters. In a given wave, enemies appear one at a time in the vertical section of the arena. Enemies come in different shapes and attack with different patterns, although all the enemies in a single wave will be of the same type. Some captors proceed straight through the arena, while others split in half, zig-zag or reverse direction.

According to programmer Steve Woita, the game was playtested by a group of young girls who kept saying, "It's not like Ms. Pac-Man." Based on this Atari decided to only produce 10,000 carts, assuming it would be a flop.

Quadrun was part of the 2005 Atari Anthology, a collection of classic games for the then-current Xbox and PlayStation 2 consoles. It was also included on the plug-and-play Atari Flashback 2.
