The awesome destructive potential of Mercs 2 is hamstrung by a litany of technical shortcomings and clunky design.
The original Mercenaries: Playground of Destruction was a pleasant surprise for me. It managed to take the GTA open-world format to a tongue-in-cheek, ripped-from-the-headlines military theater that was essentially an international buffet of stuff to blow up. Mercenaries 2: World in Flames changes the theater from a fictionalized North Korea to a fictionalized Venezuela, but the basic idea is pretty much the same. With the added power of current-gen consoles, this should be more than enough for a good time, but sadly, there's a bevy of design and technical problems that keep Mercs 2 from being all that it could be.
