Atari 7800 versionOn the Atari 7800, the name of the game can be taken literally. Due to a bug in the program the NTSC release cannot not be completed. Some of the items you need are hidden under terminals that cannot be searched. This was fixed for the PAL release.
Commodore 64 PAL and NTSC versionsOriginally the game was released in USA in NTSC version by CBS. A few months after the premiere it was also published in Europe in PAL version by US Gold. However it was released with a glitch resulting from the positioning of the code for the electricity bolts. If a robot's firing pattern calls for it to shoot on the far left of the screen, the agent would be fried no matter where in the room he was. Eventually US Gold patched the game to prevent the robots firing in this situation but a proper fix was implemented in 1997 by cracking group Remember.
DevelopmentAccording to Dennis Caswell, the development of the game took about ten months. The idea behind came up from the movie War Games - the HAL-like computer led to the idea of a platform game in which the player was required to infiltrate a computer-controlled complex. The first thing that was created was the animation of the running man. For a long time the game had no title. It had changed prior to the release where somebody noticed the similarity to the TV show Mission: Impossible but due to obvious reasons it could not be used. Author cheated and gave it a title that was legal while still creating the desired association. The graphics were drawn on graph paper and converted into hex strings that were hand-typed into the code.
References to the gameThe title of the German computer games podcast Stay Forever by former gaming journalists Christian Schmidt and Gunnar Lott is inspired by the synthesized speech "Stay a while...stay forever!" from this game. The voice is also used in the podcast's intro.
SpeechOn the Commodore 64 version. The game is well known for the use of synthesized speech. Electronic Speech Synthesis (the company that developed the sampled speech for the game) used this game as a test sample.
When this sample was a successful game, Electronic Speech Synthesis (ESS) significantly raised their prices. This caused Epyx to never use their services again (although Impossible Mission II uses ESS, Novotrade developed the game, and they were the same sampled speech tracks used in this game).
