Commando

Commodore 16, Plus/4 versions

The official release by Elite for the Commodore 16 is rather simplistic with 4 directional controls, no scrolling, and contains only 5 singlescreen levels. C16 coder Richard Ikin later explained that it was his first programming job, he was required to do everything himself, with no senior staff supporting, and no development tools beyond graph paper for the graphics, and notes that the game does not scroll as he had no idea how to make a C16 screen scroll, having basically blagged the job with minimal 6502 knowledge (and nobody checked). There is also a 48KB Commodore Plus/4 specific (presumably homebrew) version, which is much closer to the Commodore 64 version in terms of gameplay, graphics and sound.
