Most Ridiculously Overpowered Weapon?

[The Great JT]

Most overpowered gun award definately goes to the rocket launcher in any game, but I'm gonna give it to the Annihilator RPG from Saints Row 2. Basicalaly, it's an RPG launcher with a following mode and a lock-on function.

It's overpowered in a good way against helicopters. But getting it is several bitches. You have to beat level 6 of the Stilwater Power Plant's Mayhem minigame. Along the way you also get the flamethrower, but it's so pathetically piss-weak you might as well just wait for Friendly Fire to get it.

Fallout 3.
There was a gun that fired 8 Fatmans

While it's true it has insane damage potential, it also has the habit of annihilating the player at the distances where it can be used accurately against tough targets, and wasting a whole lot of ammo on coating the surrounding area (unless you're trying to annihilate entire legions with it) at distances where it's not.

barrets ultimate weapon in ff7 when you cause it to do overflow damage thats just cheap

A lot of games have "that weapon." You know. The one that makes the game practically impossible to lose once you find it?

The Alucard Shield of Castlevania: Symphony of the Night. By itself, ordinary shield. Better defense than the other ones, nothing special.

But power it up with the Shield rod and this normally defensive item turns you into an unstoppable death machine. Enemy projectiles that hit it turn into hearts AND health. Any enemy you touch is dealt a ludicrous amount of damage AND it heals you. All you need to do is literally stand on a boss monster's foot and it will die in seconds.

Galamoth, supposedly hardest boss in the game, down in less than a minute with this thing.

Oh, but it drains your magic. Might be a problem if it didn't regenerate by itself over time.

Don't forget the Crissaegrim.
