LucasArts has put the video trailer for Mercenaries up on the official site. The game's official name is apparently Mercenaries: Playground of Destruction, but it should secretly be Mercenaries: Blow everything the hell up, because that's what you do.
Is the dialogue really forced sounding? Yes. Is the military setting overused? Yes. But... did the game look really awesome, fun, and possibly a tiny bit unique in person at E3? Well, yeah actually. As has been said elsewhere, nobody's head was exploding due to awesomeness overload, but it at least looks like the good folks at Pandemic are trying with Mercenaries, and they're a talented bunch.
