ok guys, I won't mention how I played it, because TFP doesn't support that kind of stuff, but here's my review so far
Helicopter controls: Perfectly fine. VERY similar to Desert Combat. The only difference is that it's easier for newbs to control it, and you can stay at a position in the air without touching anything. Let go of keyboard and mouse and you hover. It played "Bird is the Word" by the Trashmen when I got in the helicopter
Infantry: OH MY GOD. The weapons are SPECTACULAR. The reloading animations are INCREDIBLE. The best part is the sound, also. My God. I love it. Huge explosion sounds and huge assault rifle sounds. Very loud and crisp. The pistol fires VERY fast now, as fast as you can click. I can unload the entire clip in about 2 seconds.
Menus: PERFECT. Very "vietnam-ish." It does what Vice City's menus did for with the 80s. Plays CCR's "Fortunate Son" (did I call it or what) during the main menu.
Intro CG: Awesome as hell. Also plays Fortunate Son.
Graphics: Good. Reminds me of Far Cry. Flora EVERYWHERE. At your home base, a radio blares news about the Vietnam war.
Loading times: No longer than regular Battlefield (at least on my computer).
My impressions so far: A MUST-HAVE. Will buy it as soon as the stores get it here. The best parts overall so far: The weapons and level design.
