Impossible Mission, which casts the player in the role of a secret agent infiltrating an enemy stronghold, is considered one of the best games for several platforms.

From 1985 to 1990, the game was released for the Apple II, Atari 7800, ZX Spectrum, Acorn Electron, BBC Micro, Amstrad CPC, and Master System.

The player takes the role of a secret agent who must stop an evil genius, Professor Elvin Atombender, who is believed to be tampering with national security computers.

The player races against the clock to reassemble and decrypt the password to Atombender's control room while avoiding deadly robots.

[citation needed] The first element of the game to be created was the player character's animations, which designer Dennis Caswell lifted from a library book about athletics.

[7] Caswell recounted: I never met the performer but, when I supplied the script to the representative from ESS, I told him I had in mind a "50-ish English guy", thinking of the sort of arch-villain James Bond might encounter.

When I was given the initial recordings, the ESS guy was apologetic about them being a touch hammy, but I thought the over-acting was amusing and appropriate, and they were left as is ...[6]The game's title was one of the last elements to be finished.

It was, at least, somewhat descriptive, and the obvious allusion to Mission: Impossible was expedient, to the extent that both the game and the TV show involved high-tech intrigue.

's Gazette in 1986 praised Caswell as "one of those rare people who has all the skills necessary to create and design an outstanding game" while software development teams were becoming more common.

Elvin's stronghold also grew in size, divided into a number of towers which the player had to traverse, all the while picking up pieces of the password.

It kept the same idea as the previous games, and mainly featured updated graphics and audio, also allowing the player to choose among three different characters.

[18][19] In the US, the Nintendo DS version was released exclusively at GameStop stores by Codemasters[20] (which, similar to the Amiga sequel, included a filter for graphics and audio to recreate the C64 original of Impossible Mission in terms of look and sound, albeit slightly remastered) and the Wii version was released in March 2008.
