The VR missions are a throwback to the original VR missions from Metal Gear Solid 2, in which players ran through tests in monochromatic environments.
The downloadable content will be available on Xbox 360 and PlayStation 3 in Europe, but only the PS3 in North America, thanks to an exclusivity agreement. According to Sony, ”The DLC will be available for PS3 users in North America, Latin America, Europe, and Japan. The PS3 exclusivity is only for North America.”
Regional exclusivity usually means limited time exclusivity - stay tuned.
