Some guy messaged me on Reddit with how to do this. I'll attach his message. This obviously affects other things too.
Here it is:

Step 1: Go to
C:\Program Files (x86)\Steam\SteamApps\common\DayZ\Addons
Step 2: Move the following .pbo files to a new folder:assets_buildings.pbo, assets_buildings2.pbo, assets_misc.pbo, structures_houses.pbo, structures_industrial.pbo, structures_military.pbo, structures_walls.pbo, plants2_clutter.pbo, plants2_misc.pbo, plants2_plant.pbo, and plants2_tree.pbo (if you can't see the file extension type in the search bar, for windows 7, "folder options" then go to the view tab and enable show hidden file extensions).
By removing the assets_buildings.pbo you will receive a error on startup (just click ok) but the game will launch regardless.
Understand this is fucking laughable because if you try to remove plants2_bush.pbo you will receive battleeye error #10 for corrupted game files and kicked off any server you join. However, remove all the fucking buildings, trees, grass, and walls (probably even more) and you can play with xray vision and a railgun.
If you do exactly as I described buildings don't exist for you (loot/players float in in midair in a 2-3 story building) but you can't go up the invisible stairs. So if you're next to a wall ground level I can run through the wall hit you and run backout out through the wall. Also although stairs don't exist people who are on the second or third floor are bouncing up and down between ground level and their current location. No idea what it looks like from your perspective but I could potentially kill you with an axe on the bottom floor while you're on the third floor, assuming I hit you when you 'bounce' back down (on your screen you never move of course).
No hacks and no scripts. No banning, only rare disconnects. Best strategy is run into a building that has no entrance and enjoy godmode with godlike vision. Railguns seem out of place in dayz, but hey if you can't beat them join them.
This works as of today.

That's all. To clarify, I never used or asked for this. He just sent it.
