Quite enjoyable, actually.
And this game's designed for this chunk of the video-game world. And it does deliver.
Graphics are very good (on HDTV, on a SDTV they're just above average), but it's in the sound department that the game really shines, it has an amazing sound quality, it really drags a gamer deep into the jungle.
Playability is designed for the casual gamer, as it gets easier in propotion to how many times one dies, it works, if not sometimes gets too easy.
In the lines of "Butcher Bay" it has no HUD, and health is á-lá "CoD2" and "FNR3" , it works for this as it worked for the former. It's a nice way of promote realism, the "no-HUD thing".
On the down side:
1.there's the glitches, some passable, some unforgiven, that in some (rare) situations, one could have the need to start everything from scratch.
2. Too short (although in my particular case, it had the perfect size, as I had other games to play).
3. The "downtown" level is not up to the "jungle" levels, as a matter of fact, it seems like a different game, it loses its "panache".
If you're not an harcore gamer, that enjoys mainly fast-furious FPS's this game might be enjoyable. Nice to play with the family as well.
