A simple mod that allows you to walk through walls and any object in the game. Replaces the backstep animation with the animation that plays when you walk through a fog gate allowing you to walk through things, everything else is vanilla. 

Keep in mind that most out of bounds areas have no collision so you will fall through the map in most cases. This can be used however to skip and bypass certain barriers in the game like going directly to the monumental at the start of the game which opens all archstones before completing Boletaria 1-1, or simply walking through the gate that blocks the access to Phallanx and walking through the dense fog that blocks you after the Tower Knight boss fight. You can even access the pantheon by walking through the wall up in the nexus, which is usually blocked when offline, specially for the RPCS3 emulator since it doesn't have online support.

To use the mod just press circle while not moving.

Compatibility: Modifies "gameparam" and is not compatible with other mods that modifies "gameparam".

-RPCS3 emulator for PC or a CFW(custom firmware) PS3
