Same non-good system like Boiling Point! Crapped off!!
The gameplay starts very average (you sit in a boat and have to defend it from approaching boats and helicopters. Either what you do, you get to the island.). From that moment on, you're free to do everything; almost. You get some advices and can place your own missions schedule, this was quite interesting, because of the variety of guys you got to talk to. But after a while you feel a bit exhausted from this always repeating pattern of talk-walk-make your mission-walk-get your money.
The sound is quite ok, from then to then a bit strange (unrealistic weapon sounds) and always the same music, which bores already after half an hour. The speakers (russian) are quite good and in a wide variety present. The lipsync in opposite it totally whacked off.
After 7-8 hours it got as boring as Boiling Point after 2 hours. It surely makes fun to play but not for long. If the developers would only have created something new and wouldn't had relied on old whooped-off engines and systems, it would surely have become a great game which had entertained me for several days or weeks!
