Eidos has a really cool Vietnam game for the Xbox, PS2, and the PC called Shellshock: Nam '67. It's a third person adventure that features lush environments and explosive gameplay that really makes war hell. I started off wading in a sea of yellow grass and surrounded by squad members, and as I entered the jungle I was blown away. Its incredible level of detail makes it one of the most immersive war games I've ever played, and the gameplay is very enjoyable.

Shellshock felt like your typical run and gun war game, but it's so cool I couldn't pull myself away. The jungle environments allow you as well as the enemy to take cover, and the gunfights are spectacular.

It's not the most realistic game in the world (You can take multiple gunshot wounds.), but Shellshock is a quality third person shooter that does a great job dropping players in one of the previous decade's most infamous wars.
