How about we throw the knifes on the trash can and replace it with something wild
Hmm.... OH
Turbo powered Pogo Sticks jumping platforms inside of a volcano and the weapon is a big boxing glove that pushes others away, eventually the volcano erupts and you get to climb up the suddenly appeared leveled up platforms to escape the volcano and once you do it you're fighting on the clouds, the winner which have the most kills gets the entrepreneur ed out golden pogo stick for the next round and a metal boxing glove that does twice the throw and damage.
Eventually a boss shows up, it's a lava dragon that breathes fire and destroys some of the platforms, his tail hitting the corners of the volcano drops some boulders, by beating him you gotta grab a boulder and shoot it on his head, if he gets beaten before he escapes the next round will be placed on a secret bonus level filled with 80's disco style designs.
Other levels could differ, like escape from the giant rainbow gorillas on the Jungle River Logsault (basicly jump between pieces of wood as platforms on a deadly river) Explode the entire stage on Destruction Zone (a post apocalyptic stadium with lot's of explosives) Ride the magical birds from Pasara Clouds (floating cloudy islands with lot's of waterfalls and greek architectures for some reason) to reach a platform to activate the bonus zone for the next round, among other stuff.
I call it, Turbo Pogo Punch, I just made that up.
