I played this game way back, a few years ago but never got the chance to tell you my opinion on it. This game is a hard one and you should prepare for dying so many times and saving as often as you can. There are lots of tough portions of this game and sometimes you just get frustrated. Watch out for Japanese come from everywhere.
The setting is great, you have jungle, riverbeds to cross and to clear. You have a little variety of weapons, yet they are satisfying.
This shows the hell war is.
Everyone should play it.
