About Impossible Mission

The situation: for three days have the strategic central computers of the great powers acted up. An unknown person manipulates their programmes; at the end of these programmes is the starting command for the intercontinental rocket. The countdown is on, only 6 hours keep the humanity from an atomic inferno. An unknown person? Only professor Elvin, the insane computer expert could crack the top secret start code, Elvin, who entrenches himself in his intangible subterraneous, guarded by 90 murderous robots, that until now had hunted down every intruder. No one who has ever set foot on the lift to Elvins cave labyrinth has returned back alive. The last hope: Special Agent 4125, the most cunning, toughest and most indiscriminate man, that the secret service can offer. Only ice cold reckoning and superior physical condition give this unarmed hero a tiny chance to avert the disaster in the last minute. The game: your task is to put a stop to evil Elvin Atombender's game. For this you have to enter in his laboratory, protected by a vault somewhere on his underground stronghold. To open the laboratory's door you need a nine letters password, each letter of which Elvin coded into a punchcard, just for cutting in four each one of them, painting them in different colors and hiding the resulting pieces everywhere in his base's furniture. So all you have to do is search into every object of every room for pieces of puzzle while surviving the robots, the pits and doctor Elvin's annoying voice, retrieve all the 36 pieces, put them together in groups of four, and head for the laboratory, where an unpleasant surprise waits you

Atari 7800 prices, all games & how to spot a fake

A computer classic that Atari promised for spring 1987 and delivered in 1988, now one of the pricier mid-library carts.

Impossible Mission was an Epyx computer game, and Atari Corporation published the 7800 version in 1988 with Man Development Corp. credited as developer. Computer Entertainer listed it in early 1987 as one of eight planned 'super games' for the 7800, all licensed from computer titles, scheduled for March. Later schedules moved it to the third quarter and then the fourth quarter of 1987, and it shipped at the end of 1988.

It is a single-player platform and puzzle game played with the Pro-Line joystick. The cartridge is rated scarce-plus, noticeably harder to find than the common color-label games.

What the press said at the time

“Impossible Mission for the Atari 7800 is an excellent game. Every game is different because the room configuration and robot behavior change with each play.”
— GamePro, July 1989

Worth knowing

From the 7800 manual. The control-room password must be assembled from pieces scattered through the complex.
From the 7800 manual. Reset restarts and rearranges rooms and robots.

Before you buy

Low counterfeit risk but a real premium: AtariAge rates the Atari color-label cart scarce-plus, so loose copies cost more than the typical 7800 title. Confirm the CX 7832 number on the label. Pro-Line joystick, one player. The box and manual carry much of a complete copy's value.
