Functional Stairs

I have created a weapon holder to solve the "fixed weapon glitch"

This weapon is set to normal physics














This plasma barrier has an invisible ledge on the bottom. Just turn it sideways, and phase it into your wall (just enough so it doesn't poke out of the wall). Then you have an invisible ledge on which you can place your weapons.

Note: You do not get caught up on it because the sides of the invisible portion are rounded.
