Okay, so I am going to build a 3 barreled plasma caster for the contest. I do not expect to win, but I will try my best. It will have 2 round barrels on top of 1 rectangular barrel. I don't know what it means by "medium". I have built a custom Wolf Predator costume and had a lot of fun. I am going to improve it, because the chest plate strap that connected to the med-pac broke. I do not expect to win, but I do expect to have a lot of fun trying. Good luck to all the other contestants.
