Developed by Spectravision, Sector Alpha arrived on the ColecoVision as an action game.

Spectravision also made Flipper Slipper for the ColecoVision.

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

Pick it if…

  • you want to fight, blast and test your reflexes
  • you have time for a quick session (under an hour, or endless arcade fun)
  • you've played the ColecoVision hits and want something less obvious

Maybe skip it if…

  • you prefer slow, thoughtful games over reflex tests
  • you are looking for something to play with friends

What playing Sector Alpha is like

Action games test reflexes and nerve. Expect fast enemies, tight controls and stages you clear by reacting quickly and learning enemy patterns.

Tip for newcomers: Retro action games are often short but tough. Treat early deaths as practice runs; every attempt teaches you where the next threat comes from.
