The game "Meltdown" is made under the Atari XG-1 Light Gun . "Meltdown" is a mediocre shooter, reminiscent of Reactor for the Atari 2600 . You need to shoot flying objects that destroy the reactor in the center of the screen. Arkanoid inside out, in short. The beginning of the game is confusing with meager graphics, but the presence of a serviceable light gun can deliver many pleasant minutes. There are 12 reactors in total in the game, and the further, the more difficult. " Meltdown" has a rather interesting manual explaining all the details, who are interested can read it.
You can run "Meltdown" on the EMU7800 emulator , but you definitely won't be able to play it. The sight, if visible, then exactly shows where it is not needed. Management in "Meltdown" is made only by a light gun.
