The Nanosuit

Nanosuit Intro

The Nano Suit in Crysis is your most valuable tool when engaging in combat. It has 4 modes, Armor, Speed, Stealth, and Strength. Modes can be changed in several ways, the easiest way is holding the middle mouse button and moving your mouse, then releasing the middle mouse button. Modes can also be changed by tapping the 4 key several times in succession. If you have it enabled in the game options you can also change by the quick select method. Pressing back twice will enable Armor mode, pressing jump twice will enable strength mode, pressing prone twice will enable stealth mode, and pressing sprint twice will enable speed mode. I highly suggest you enable this in options, unless you find that you accidentally switch too often.
