User blog comment:GeneralOwnage55/What is your idea for a new plasmid?/@comment-1671655-20100131070330

A plasmid that created a shield in front of you. It's temporary, and you can't use any weapons/plasmids with the shield up.

Also, how about a plasmid that can create a shockwave? (Kinda like when the Bouncers stomp on the floor and Jack becomes disoriented).
