Hired Guns is a sci-fi RPG developed by DMA Design and published by Psygnosis in 1993 for DOS and Amiga.
The game allows you to control 4 mercenaries, with a split-screen that shows the point of view of the different characters that can move in the 4 directions (Eye of the Beholder-style).
The gameplay was highly innovative, with monsters that can move freely around levels and pursue the characters, many different armies with different effects, underwater areas, inventory management that will change depending on the character, and much more. But what made the game unique was the possibility to move the mercenaries independently and have them interact in different ways. The game was also supporting multiplayer, with up to 4 players controlling the heroes.
Hired Guns is considered by many of the best games ever released on the Amiga.
