Definitely a few bugs but overall it is worth playing. It entertained me and thats all that matters to me.
I just love blowing things up whether I'm using an RPG, tanks, helicopters, etc. The sort of mini games where you can wager money for completing the mission given by your crew is fun especially since this could be a means of cash resource but just doing the regular mission will give you enough cash to buy everything that you need.
Pandemic definitely could have improve the game with wider selection of weapons and vehicles and an ability to store the weapons and vehicles in the headquarters. They could have resolve some of the bugs & glitches before release and clean up the game a bit. The graphic could have been improved as well. If Pandemic spend more time with this game this could have been a major blockbuster hit.
Note that I didn't pay for the game and just rented it so if you are not sure if the game is for you just rent it and then you can decide. The game is actually pretty short so you can probably finish the game in 1 or 2 Hollywood Video or Blockbuster rentals.:)
Overall Mercenaries 2 entertained me and thats all that matters to me.
