I understand this is a "ownage" weapon to destroy everything.
Here are the reasons why I don't like this.
Blockhead 1: Doop Deep Doorop, oh look! A mega shot-gun!
Blockhead 1 picks it up.
Blockhead 1: Lol, it's so big, the barrels are all over my screen! :D
Blockhead 2: Oh look! A sniper!
Blockhead 2 picks it up.
Blockhead 2 gives a instant-kill on Blockhead 1.
That's how it goes, due to the huge amount of barrels that would make the gun HUGE. It would cover your entire screen and it would also make you spotted.
Why not just use the Sniper, it's faster, it's a 1 Shoot Kill, It does not cover your entire screen..
Or if you want something that kills EVERYTHING...
Someone do a Rocket-MiniGun.
So personally I love and hate the idea.
