the U3 is called "it" by lord saddler the easyest way to beat him is with a fully upgraded striker so says my friend but he relates to brute force i have found a harder more gentleman like approach dodge his attacks and make it to the end then...GET OUT YOUR ROCKET LAUNCHER!(prefferabley infinate) AND FIRE AWAY! if you run out the normal shot gun will work if you run out of shells use your grenades and shoot the gas barrels (so strangely placed by the way) and beat the livin HELL outta the u3!!!("it") after that continue to the end...make the thing suffer for me will ya!!!

you could do that or you could do it the even more fun way and whip out your infinate chicago typewrite and just completely annihilate the little crapper!!

What the is U3? If you tell me what its actual name is i will help u but until then i cant. i have beaten the game 3 times once on professional and 2 on normal so i will definitely be able to help u. So respond back

To beet "it" (not U3) is to find two buttons to release the cage from hanging, but be careful you only have 30 seconds to evacuate when you hit both buttons. Dont forget to hit the green buttons to unlock the gates blocking your path. Do this repeatedly two more times.When you get out of the cages it is time to battle "it". Use the red explosive barrels to deplete his life and lock it out by closing gates (the perfect time to unload on it. After a while it will dig into ground. Keep your hands on the control because it will try to keep snapping at you from underground. When it comes up to surface keep shooting it. It will soon die and then you will get an award of 50,000 peas!
