Find some water to swim in. Then equip two weapons that are easy to see,such as an assault rifle or a sniper. Remember to get two of the large guns. Then jump into the water and summon an object that says you need to throw a smoke grenade,get out of the water, and both guns will be holstered at the same time! P.S: to unholster a weapon, pull the right trigger and then you will throw the smoke grenade.

Go to PMC's front courtyard and there will be two staircases. Summon the norse wind,and drive up the stairs.You have to wheelie, or it wont work. If you do it right,you should fly off the bike.But,you fly througn the wall at the top of the guard tower!!MAN CANNON!!!!!!!!!!!!!!!!!

Ok there are some glitches never reported that I found. Just for the record.

I WAS THE FIRST TO FIND THESE GLITCHES ON 9/13/08Ok here they are

1. Walk On Water
To Do This,
Stand Near Any Lake Or Water,
Get A Enemy Shooting At You Perferable Rpg but Grenades will do
Ok heres the tricky part, Right As The Grenade or rpg blows up run into the water
By doing this, you body should fall in water and doing correctly will have you walk on water.

2. Never Die
Ok this may only be done on the first PLAV HQ mission. This also requires your xbox power pack to get really hot.
First Start Mission
Second Save And Quit
Third Continue From Last Save Point
Fourth Let You Xbox Powerpack Overheat To The Point It Is Hot To Touch
Fifth Get Hurt To The Point To Where You Are 2 HP Only And Run Away
Last Wait 10 Second And if You Havnt Regenarated You Are Now Invulerable !!

3. The Constant Click
To do this you need 3 pmc upgrades that HAVE NOT been bought yet.
Ok you have to do this fast but buy all 3 upgrades in a matter of 5 seconds
If done correctly when you leave there will be a constant clicking noise untill you die.

Here is a great way to get easy fuel. Make sure you have recruited the jet pilot in your PMC, then go talk to him inside the PMC headquarters(he has a couch set up on the right side of the upper-floor). He will offer you the option to do his air-strike challenges. Complete the air-strike challenges and after EACH time you complete one, exit the PMC, walk out the FRONT door and continue straight down the main entrance to the PMC, until you reach a grassy hill, walk over this hill and slightly to the right until you reach the same area were the air strike challenges take place, it's just over the top of the hill. There should be lots of oil cans laying around from the air-strike challenge. Enjoy your free oil!
