I judge games by graphics, and found these to be more than acceptable. Lush green enviroments, overcast and smoky citys aflame amidst the carpet bombing. There is a level that is in an old buried temple that at times is absolutely gorgeus. Sound is the one weak point. M60, AK47, and M16 are your primary weapons, and they sound to soft for killing.
Enviromental sounds are perfect though, running water, nature, etc.
Basically, you are a soldier in Vietnam, trying to eradicate the Vietcong soldiers. In the game, they are portrayed as fearless and brave. The Vietnamese soldiers were really short and the strategy was a bit confusing. The Vietcong would often run at me fearlessly and start shooting. The sky looked like a medley of colors or better yet, a fog.
