Pretty much what the header says, what's your favorite method of over-kill in a game. A tribute to those weapons that are so insanely over-powered that the only sane reaction is maniacal laughter.
Mine is the Akimbo enabled alt-fire of BLOOD's Napalm Launcher.
The alt-fire was formidable indeed, setting off cluster-bomb style fire bombs across a map... but with the Akimbo power-up, you would witness fire power so awesome that your frame-rate would grind to a near stand-still in witness to the awesome display.
There's 3 weapons that are all fairly equal as the "best" over-the-top ridiculously awesome weapons. These are, in no particular order:
1) The Black Hole Cannon from Mass Effect 2. I mean really, it shoots black holes. There's not a whole lot more awesome than that.
2) The Topsy-Turvy Bomb from Armed and Dangerous. This thing is nothing more than a giant corkscrew you plant in the ground and the world turns upside down, sending all your enemies falling into the sky. Check @2:50 in the following video to see it in action.
3) The Landshark Gun also from Armed and Dangerous. It's a gun that shoots a shark that swims through the ground and it launches out of the ground and eats enemies whole. Once more, see below to see it in action.
