This glitch allows you to shoot fully automatic with any weapon in the game, with unlimited ammo just by holding down the trigger.

*EDIT*

I forgot to include to put different camos on each FAL. For one, the FAL you hold will switch camos when you switch to your noob tube, and two, it may help do the glitch.


First you will need 2 classes -

FAL Grenade Launcher
USP .45 (not comfirmed that this is the only secondary you can use, but I know it works. It also looks cool when you do the glitch.
Semtex (or anything you can kill yourself with. You can also jump off something hgh if you don't have Commando.
Everything else is up to you. These perks matter none.

You also need another class-

FAL Bling (Red Dot Sight and Grenade Launcher) WITH DIFFERENT CAMO THAN THE FIRST ONE
USP (again, not confirmed that this is the only secondary)
Perks are whatever you want.

Now, follow these [tedious] instructions.

1. Shoot a few bullets out of your FAL

2. Kill yourself (yay Semtex!)

3. Switch classes to bling FAL (you can also do this before step 2)

4. Switch to your USP and pick up your old FAL

5. Shoot both of its nades

6. Switch to your bling FAL and pick up the USP

7. Switch to your FAL and let it reload, then press left on the DPAD

8. Hold down the trigger and watch your gun go crazy!

You can actually do this with any assault rifle if you still follow the directions.

Now for the any gun part.

You can do this with any gun by switching your USP with it, pressing left on the DPAD, and holding down the trigger.
You do have to keep the FAL, or the assault rifle you chose to do the glitch with.

The coolest I've seen are the Deagle (akimbo is awesome) Intervention, FAL, Magnum (akimbo is also awesome) .50 cal, and FAMAS.

Once you've done the glitch, you can reload, run, switch weapons, or whatever you want except climb. This will take away your just until you press Y.

Anyways, it's a pretty awesome glitch, and if you have any questions, post here. If you want I can also help you in-game.

Peace
