The Conduit Cheats

Hop the Invisible Wall in Gridlock
At the end of Mission 5, Gridlock, there is a Drudge ammo cache in the far right corner as seen from the entrance. Hop onto it and, from there, hop onto the hedge directly in front of you. Walk forward a few paces and drop down to your left. If done correctly, you should be on the other side of the invisible wall around the helicopter.

Charge Exploit
On weapons that may be charged up (e.g. The Deatomizer and Strike Rifle), charge a shot, melee, then press reload quickly and the charged shot will be stored for use -- and you don't have to hold down the trigger! Press the trigger once to release the charged shot.

Useless Flashlight
In a multiplayer battle, acquire a chargeable weapon (Strike Rifle, Warp Pistol, Deatomizer) and charge it up, then press the pause button. You will hear a firing noise, but you won't see a bullet (although ammo will be depleted). After unpausing, a small remnant of light will be leftover on the gun. It will not be apparent to opposing players and will stay with you till you get killed. It does nothing to enhance gameplay, whatsoever.

Extra Shotgun Ammo Exploit
In multiplayer, while already equipped with a shotgun, look for a shotgun on the ground . Once you use up all of your rounds, start reloading and walk over the shotgun on the ground (right when you see the reloading animation). You should load 8 shots normally, but the reloading animation will then continue and you will end up with 15 bullets ready to fire!

Air Brakes
In multiplayer, when you fall or jump off a building, press pause and you will float. This will prevent you from dying or losing health.
