You can acquire extra ammunition for the Gauss sniper rifle by equipping a SCAR with a Gauss attachment. As you pick up ammo, you'll receive a prompt indicating that you have no ammunition for the weapon, but you'll be able to fill up your reserves just like you would with any other weapon.

Joke's on you. There's no such thing as New Game Plus. Your weapon attachments, armor modules, collectibles, traffic cameras triggered, and nano-catalyst collected are simply saved to your Crysis 2 campaign career. When you replay a mission, you will have all that stuff available and unlocked from the get-go.

If you're invisible when you fire your weapon in multiplayer, you will drain your energy gauge entirely. Be sure to turn off invisibility right before you fire your weapon to avoid depleting your energy.

Play the "Dead Man Walking" level. After getting the "Locate the Nanosuit Deep Scan Cradle; Locate Gould" objective, you will find an elevator at the end of the level. Take the elevator down as instructed. When the elevator door opens, follow the hallway like normal. After the first right turn notice the security camera next to some servers. Jump over the red rope and get close to the switch on the right. Hold [Action] and a red light should appear. Return to the elevator that you used, and jump over the red rope to reach a second elevator. The switch should now be lit. Hold [Action] again, as instructed. The elevator doors will open, showing a C.E.L.L. dance party.

Successfully complete the game. Press [Fire] five times during the credits to play a hidden mini-game.

Successfully complete the game. You can start another session with all previously earned armor modules.

If you have Air Stomp you can jump off any sized building and and survive as long as you activate it. For instance, in Dead Man Walking you can jump off the starting building and do an Air Stomp and survive without any loss of health.
