If you've already picked up your copy of Resident Evil: The Mercenaries 3D for Nintendo 3DS, then you've also probably already played the preview of Resident Evil: Revelations, which is included as a special feature. If you haven't, the preview is about five minutes worth of gameplay, and it's a great peek at what we should be seeing next year in the full game.
It's a shame we couldn't record the preview in 3D; even in this short span the developers managed to work in some truly scary 3D effects—note the bats flying at the screen and blood spatter on the windows—and that's before you factor in the B.O.W.s that will do everything in their power to finish you.
Even in this short blip, storyline begins to emerge as you find a man tied to a chair, electrical wires destroyed, evidence of violent bloodshed abound. You can definitely tell you're in a Resident Evil game. It looks like Revelations is moving towards a mix between old and new Resident Evil, that is if the full game has the same mix of tension and action as the preview.
Definitely looking forward to the full experience, set to release on Nintendo 3DS in 2012.
