Juno First is intended to be an Atari 2600 port of the arcade game of the same name. Naturally the Atari 2600 version requires some significant simplifications, but the main elements are there. The visual style of the game is similar to Beamrider, but it plays quite differently.

The awesome sprite graphics were created by Nathan Strum, and the the excellent title music was created by Erik Ehrling (moderntimes99).
