WORST GAME EVER!!!!
This would have qualified as a "game" back in the mid 80's when game developers started to develop the concept of a PC game. By today's standards, Marine Sharpshooter 3 is several generations behind.
I don't know what the game developers were thinking when they published it, but one thing they need to know is that today's gamers are very sophisticated.
This "game" has very poor graphics, kind of primitive.
