When there's dirty work to be done and you're looking for a hired gun, looks and originality don't matter much-all that matters is whether they can get the job done. You can approach Mercenaries 2 in the same way, letting it do its thing instead of obsessing about its shortcomings. Sure, it isn't exactly pretty and it doesn't reinvent the wheel but it does pack a nice satisfying punch.
THE BOTTOM LINE: Don't let its shortcomings get you down: Mercs 2 may have its faults but it's still a pretty fun title that kicks a fair amount of ass.
PROS: Loads of action; great setting and plenty of cool things to do; lots of different weapons and vehicles.
CONS: Mediocre presentation; paper-thin story; derivative open-world design.
