So we here at Kotaku (and by "we" I mean "the Interns") were going to briefly demo Resident Evil: The Mercenaries 3D's Co-Op gameplay for you-but being the forward-thinking young professionals that we are, we thought, why not kick it up a notch?

What ensued we have christened "Extreme Co-Op"— and it involves playing the game while only looking at your partner's 3DS screen. You should try it. You should try it now.
