Poseidon Wars 3-D is a shoot 'em up released in 1989 for the Sega Master System, developed by SEGA. It blends shoot 'em up and simulation elements.

It landed about 3 years into the Master System's life. Other notable Master System releases from 1989 include Wonder Boy III: The Dragon's Trap, King's Quest I and Psycho Fox.

SEGA also made Alex Kidd in Miracle World, Phantasy Star and Hang-On for the Master System.

Poseidon Wars 3-D 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 Master System hits and want something less obvious

Maybe skip it if…

  • you dislike high difficulty and screens full of bullets
  • you are looking for something to play with friends

What playing Poseidon Wars 3-D is like

Shoot 'em ups (shmups) put you in a ship facing waves of enemies and bullets. Runs are short and intense, and the goal is to survive, collect power-ups and push your high score.

Tip for newcomers: Focus on your ship's small hitbox rather than the flood of bullets, and learn which power-ups suit each stage. Most shmups are designed to be replayed many times.
