Here's the latest trailer for Metal Gear Solid 3DS straight from Nintendo's Japanese media summit today. I really like how Kojima and his team reworked some of the game's key moments to emphasize the 3D effect, and they look good even in plain old 2D. Those effects are going to be spectacular when the game ships in the spring.
In my opinion Snake Eater is the best game in the series, both for its less-than-ridiculous plot and its deep gameplay. Supposedly the 3DS version will include some elements from Peace Walker as well, and Kojima is a developer who uses every last feature a platform has to offer so I'm optimistic. I just hope the new game lets you select different camo quickly with the touch screen; backing in and out of that camo menu was one of the few issues I had with the original game.
