Impossible Mission is a platformer released for the Sega Master System, developed by Epyx and published by U.S. Gold. It blends platformer and action elements.

Epyx also made California Games and Andre Agassi Tennis for the Master System.

Impossible Mission is a single-player game, so it's one to enjoy at your own pace.

Pick it if…

  • you want to run, jump and explore
  • you have time for an evening or two (roughly 1–6 hours to see it through)
  • you've played the Master System hits and want something less obvious

Maybe skip it if…

  • you get frustrated by precise jumps and limited lives
  • you are looking for something to play with friends

What playing Impossible Mission is like

Platformers are all about movement: running, jumping and timing your way across levels full of gaps, enemies and secrets. The best ones feel great to control within seconds and then slowly teach you to master every leap.

Tip for newcomers: Retro platformers often have limited lives and few checkpoints. Learn one level at a time, look for hidden 1-ups, and don't be shy about using a save feature when it is available.
