This game is pretty good, I have it on ps2. Some parts are challanging but that makes it fun, just about everything can be destroyed. I just got it yeasterday and trying to get the helecopter is a pain,but once I have it that will be awsome.
Mercenaries 1 and mercenaries 2 have their differences, for starters 2 has new vechicles and weapons, but in 1 you can have as many items or vechicles delivered to you. I personaly think that Mercenaries 2: World in flames is worth buying.
