Following the success of Metal Gear Solid was Metal Gear Solid: Integral, known as VR Missions in North America and Special Missions in Europe. The Japanese release came as a bonus disc, packaged with both discs for the original Metal Gear Solid. However, the original MGS had a few additional features. These included a silenced MP5 submachine gun which Snake would start the game with on easier difficulties. Possibly the best feature of Integral's VR Disc is that, for the first time, players were able to take control of the Cyborg Ninja for a set numer of missions.
