Quoted from HOOKED:We have some ideas for casting just waiting on game play. We made custom pops for TNA, tron, Bksor, Twd, AV etc if you want to compare quality.
I believe I read from someone involved with the game (can't remember who) that the pop bumper has RGB lights in it and when lit different colors, means different things. So whatever mod is done to the pop bumper needs to keep this in mind. I believe that was said when someone suggested putting a Plasma cap on it.
