Forum:Shield mods?

I was flipping through the instruction manual the other day (after having already beaten the game), and noticed mention of mods that are supposed to change or enhance the way shields behave. However, I'm heading toward the end of my second playthrough now, and I've never seen one. Do these exist, or are they something that was cut from the final game? 173.80.109.181 11:06, November 5, 2009 (UTC)
