You'll be granted the lethal, cloaking friendly Predator Bow, a unique weapon skin for the bow, and the all-seeing Recon Arrow on day zero. You'll start multiplayer at level 5, letting you evolve faster than your prey. You'll get immediate access to the silent & deadly "Hunter" Nanosuit module, a powerful perk perfect for the included Predator Bow. Finally, you'll be able to experience Crysis 3 and the original Crysis together at launch when you preorder — but only for a limited time!Go to: http://www.origin.com/us/about
