In multiplayer on Crysis 3 for the PC, PS3, and Xbox 360, you can reboot your suit, which is kind of the equivalent to prestige mode in Call of Duty. Your XP, ranks, unlocks, skill assessments, and loadouts will all reset, but you’ll keep your stats and you’ll get some rewards in the process.
To reboot your suit, you just need to go to the Multiplayer menu and select Nanosuit Reboot. This will take you to a verification screen explaining what will reset, and the rewards you will receive.
You can’t undo this process, so make sure you’re ready when you reboot your suit.
