Predator 2

The game is a crosshair shooter influenced by Operation Wolf. The viewpoint is from slightly behind Harrington, while the game scrolls on as you clear each section. Mouse control is offered on 16-bit versions. Your armour must be kept functional by collecting top-ups, and there are weapon power-ups such as machine guns and rocket launchers to be had. You can't go in all-guns-blazing however, as killing a single innocent causes Harrington to lose his job (mobygames.com)
