Cartridge #4 plays three games: Naval Battle, Speed Ball (a PONG variant with bumpers and "ball slide" line), and Blast Away (aircrafts shooting game). Like cartridge 3, this cartridge does not use extra controllers as it only uses the knobs and pistol of the console. This cartridge is extrememly rare, probably because no ordering flyer was originally provided with the console (which would mean that it was released later in 1977).
