Released for the Sega Master System, Mercs is a shooter developed by Tiertex and published by SEGA.

It is part of the Mercs series. The series also appears on other systems with Senjou no Ookami II ~ Mercs (Genesis). Tiertex also made Winter Olympics, World Cup USA '94 and Star Wars for the Master System.

Mercs 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 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 are not a fan of fast-paced aiming and twitch reflexes
  • you are looking for something to play with friends

What playing Mercs is like

Shooters are built around aiming and firing, from first-person corridor blasters and light-gun games to run-and-gun stages and multidirectional arcade shooters.

Tip for newcomers: Retro shooters were designed for CRT TVs and original controllers; light-gun games in particular need special hardware or alternative controls on modern screens.
