Metal Gear Solid HD Collection comes into its own on PS Vita by using the portable system's unique control methods. Use the touchscreen to select your weapons and items, look around corners and even mend broken bones in Snake Eater. Controlling various versions of spy and special operations soldier Snake, the Metal Gear games drop you behind enemy lines for a variety of perilous missions. Whether you're in the metallic hallways of Metal Gear Solid 2 or the humid jungle of Metal Gear Solid 3, armed guards are everywhere. Direct confrontation is unwise, so sneaking from location to location is essential. Sentries investigate sounds, shadows or movement, so you have to be creative to prevent discovery.
