As a classic action-puzzle platformer originally released in 1984, Impossible Mission casts you as Agent 4125, racing against a six-hour global countdown to stop the villainous Professor Elvin. The core gameplay loop involves navigating a robot-guarded underground labyrinth to search furniture for 36 puzzle pieces that form a nine-letter password. Your unarmed hero must use precise platforming to survive pits and evade ninety robots to unlock Elvin's lab. Its distinctive feature is the demanding integration of meticulous searching with arcade evasion, often punctuated by the antagonist's synthesized voice.
This is a classic action-puzzle platformer, initially released in late 1984. The premise casts the player as Special Agent 4125, tasked with a critical, time-sensitive mission to prevent global nuclear war. Strategic central computers across the world are being compromised by an unknown entity, initiating a countdown to atomic conflict. With only six hours remaining, the source of the threat is traced to the subterranean stronghold of the deranged computer expert, Professor Elvin Atombender. This underground base is heavily defended by ninety lethal robots, and no previous intruder has ever returned alive.
The primary objective requires the player to infiltrate Elvin's laboratory, which is secured by a vault requiring a nine-letter password. To construct this password, Agent 4125 must locate thirty-six scattered puzzle pieces. These pieces are derived from nine original punchcards, each cut into four segments, and hidden within the furniture throughout the sprawling underground complex. The core gameplay loop is a demanding cycle of exploration, searching every object for these vital fragments, and surviving the constant threat of robotic patrols and environmental hazards like pits.
The player character is described as unarmed, meaning success relies entirely on precise movement, platforming skill, and tactical evasion rather than direct confrontation with the automated defenses.
What distinguishes this title within the arcade and platform genres is the mandatory integration of a complex, time-sensitive collection quest with demanding physical navigation. Progress is entirely gated by the successful retrieval and assembly of the password components. A distinctive feature is the antagonist's direct interaction; Professor Elvin frequently communicates with the player using synthesized speech, adding a layer of psychological pressure as the six-hour global deadline looms.
The base is structured as a multi-room labyrinth requiring systematic searching. Players must meticulously examine furniture, as this is where the crucial password pieces are concealed. Failure to gather all thirty-six pieces before the time limit expires results in mission failure. The entire experience emphasizes spatial awareness and careful resource management (the pieces) under extreme pressure.
Since its original debut, this main game has been ported across a wide array of systems, including the Commodore 64/128/MAX, Atari 7800, ZX Spectrum, Sega Master System/Mark III, BBC Microcomputer System, and later versions for platforms such as the PlayStation Portable and Wii. The game's enduring concept is evidenced by its history of remakes and remasters across different eras of gaming hardware.

“Stay a while, stay FOREVER!” Race against the clock to gather the pieces of a secret password, platforming through 32 rooms and dodging 90 different deadly robot guards to stop the evil plans of the sinister Elvin Atombender in this all-time classic, now remastered for Steam.

Re-imagining of the original 1980s classic Choose from 3 characters New tutorial mode 3 game modes Full games haring on PSP It's hard to believe that it was twenty-five years since the original release. Impossible Mission was the first game to use real synthesized speech, an incredible development when first unleashed on the 8-bit formats. The original game included a random game-map system which ensured that no two games were the same. Although the original still stands the test of time today, inclusion of brand new graphics and sound ensures that Impossible Mission is primed to thrill a brand new audience. The gamer takes the role of a secret agent attempting to stop evil genius Professor Elvin Atombender who has been tampering with National Security Computers. Players must penetrate Atombender's base, attempting to recover parts of the system password whilst avoiding deadly robots in a race against time. Whilst the game has been re-written from the ground up and features new graphics, 3D objects, new Sound Effects and Music, the gameplay remains impressively loyal with the game layout changing for every new game. There are now three main characters to choose from plus a brand new tutorial mode. The player can now chose from three game modes, new, original and for the purist; a hybrid mode with the original gameplay using the updated graphics. The PSP versions offer an unusual feature which allows players to send a full copy of their game to a friend by Wireless so they can try it for themselves.

The evil Elvin Atombender returns in this modernized version of Epyx's original game. Elvin has assembled a crack team of robots within his high-security tower - the only way to stop him unleashing them is to destroy them first. Gameplay is puzzle-oriented as before, although the levels are now scrolling, and as such much larger than before. Each one contains objects to pick up to enable you to take on the level's final puzzle of putting them together in sliding-block form. There are lots of bonus games, ranging from a Simon title to standard shoot 'em ups.
