Air Attack is a game for the Commodore PET, a series of personal computers produced in the late 1970s and early 1980s. The game is a simple shoot-'em-up where the player controls a plane at the bottom of the screen, shooting at enemy planes that fly across the top. The objective is to destroy as many enemy planes as possible while avoiding their attacks.
The developer and publisher of Air Attack are unknown, which is not uncommon for early computer games, especially those created for platforms like the Commodore PET. Many games from this era were developed by hobbyists or small teams and distributed informally, often without proper credits or documentation. The Commodore PET was popular in educational and hobbyist circles, and many games for the system were shared through user groups or magazines.
Given the limited information available, Air Attack is representative of the early gaming scene on the Commodore PET, where simple, text-based or low-resolution graphics games were common. The game's mechanics and design reflect the technical limitations of the time, with straightforward gameplay and minimalistic visuals. Despite its simplicity, Air Attack would have been a typical example of the kind of entertainment software available to Commodore PET users in the late 1970s and early 1980s.
