ENERGY SHIELDS
As seen in today's footage of the Secret Level AC episode. Not only is that shield mounted on the arm, but it's an ENERGY shield rather than a PULSE one, interesting. (3rd gen has my favorite variety of shields, and the clip above is from a scene that never made it into the game but was in a Gamespot trailer.)
I wonder if in game, Energy Shields will serve a different purpose? Like the defensive values are constant so no Initial Guard, or the IG is weaker than Pulse shields(but doesn't take a while to build up like the Pulse Scutum) but so is the heat buildup(instead of just being one time per use like with Pulse). That would differentiate it from the defensive stat burst of Pulse shields, so they won't have initial guard values.
So if true, now there will be PULSE, ENERGY, and CORAL type shields. Unless From Soft does something with the Solid shield in the files(I'm guessing it'd have to be an AP shield, and that it breaks once it runs out, either that or having it up reduces by a lot in exchange for it's defense values.
