Hired Guns

Hired Guns is a computer role playing game produced by DMA Design
(distributed by Psygnosis) for the Amiga in 1993, set in the future. In
which you control four mercenaries, controlled though separate windows in
the playing screen.

The game could be controlled via mouse, keyboard, or (modified) Sega joypad
to allow for extra functionality.

The plot is that your band of mercenaries have been picked from
intergalactic 'non persons' and wanted criminals, and have been hired to
shut down a mutation producing plant on an artificial planet called Graveyard.

The game was advanced for its time, allowing up to four player to play
simultaneously. It was one of the earliest games to play from the three
dimensional first person perspective, a style which was later popularized by
Doom and Quake.
