Aside from the plot, the numerous enemies you face, and the suit you wear, a major focus in Crysis 3 is on the armaments you'll equip throughout the game. The weapons available to you are available in both human and Ceph design, and serve as the most deadly weapons mankind has ever known, or encountered.
The following guide serves as a primer to all the weapons available to Prophet, the game's protagonist, and the attachments you'll be able to configure these firearms with. Many of these weapons can be customized in a wide variety of ways. Assault weapons, for example, can be configured for the barrel, underbarrel, and sighting options.
