New camera options and a new way to move around are part of Metal Gear Solid: Snake Eater 3D, according to a Japanese retail listing.
For those who want to play from the first-person perspective, that is now an option. Players can also use an over-the-shoulder camera. The same retail listing also revealed that players can now move while in the crouched position.
Metal Gear Solid: Snake Eater 3D is set to release in Q1 of 2012 in North America.
