A helicopter crew of an elite American commando unit (Navy SEALS), has been kidnapped in Beirut by terrorists. A group of five of their comrades has been sent out to infiltrate the terrorists' headquarters, rescue the hostages and destroy their stockpile of Stinger missiles. You have to sneak up on the terrorists who are heavily armed, make sure they haven't seen you, then shoot them before they do the same to you. A single shot will take you down too! This is a very tough game I must say. The excessive difficulty makes it one of the harshest games you'll come across. Unlike the vast majority of run-and-gun games in which enemies are dumb, Navy Seals features enemies who shoot on sight. I never did it to the end I must confess!
The game is an excellent example of how far the Amstrad CPC+ home-computers and the GX4000 console hardware can go, I believe. Navy Seals showed more than a hint of the capability of the GX4000. As a cartridge-only release, it made use of the console's extra features, boasting smooth scrolling and excellent animation. The graphics are awesome and superior to other 8bit versions (i.e. the Commodore 64 micro-computer), with beautiful backgrounds, loads of colors and smooth sprite animation.
The sound features a pretty nice intro-music theme but the in-game SFX are poor (gunshots etc) which is rather awkward here.
