Yes, you can use the glitch. My sister (Funny_Pillow) discovered this trick, so credit goes to her.

What am I? The Glitch Adviser? Sorry, I didn't mean to be rude. Well, you're going to ask what it is and how you do it sooner or later, so I'll post the glitch for you right here.

This is a little glitch that lets you go through certain walls, even into out-of-reach areas! All you need is the Mega Rocket Turret (the Mini Rocket Turret doesn't work as well) and a nearby Gadgetron Vender (since the PDA stupidly doesn't provide Megacorp weapons).
1. Go up to a wall you'd like to try to go through and take out the Turret.
2. Stand against the wall and throw a turret as close as you possibly can to each side of Ratchet.
3. Now place another turret or two between the ones you just threw and Ratchet. This should cause the screen to shake.
4. Try to place another turret in the crammed space. The turrets may just fly out or cause you to fly out too, so be sure to have a secure area to work. Also, you have a limited time to do this because the turrets will blow up after a while, and it's difficult to replace them, so move fast! You only have a maximum of 12 turrets, so use only as many as you need.
5. This does NOT work with every wall, so don't try a wall more than three or four times. If you run out or fly out of the "crowd", you'll have to go buy more turrets and start over (like I said, the PDA is usless in this glitch). There is only a slight chance this glitch will work, so if you're lucky enough to actually get through the wall, be careful of "traps" and enjoy!

Oh yeah, this glitch also works in R&C1 and 2 with the Decoy, and it's also much easier and more accurate that way. Credit goes to my sister, Funny_Pillow, for discovering it in R&C2.
