15,000 knights are charging at you in full plate mail and all you're armed with is...

[Kollega]

Any R&C weapon,preferably R.Y.N.O. When you have entire population of murdertown in front of you,accept no substitutes.

 

[ctf1990]

The Dead-Ringer from TF2

Fuck trying to fight them. I'm getting outta there.

Unless they are surrounding me, then I would have a flamethrower. Cook 'em right then and there.

 

[lizards]

holy hand grenade

edit:fuck someone beat me to it

 

[WolfMage]

Experimental MIRV + tgm = FUCK YEAR!
And for you non-Oblivion-ers, "tgm" is Bethesdas version of god mode.
Literally, Toggle God Mode.

 

[CounterAttack]

Sasha, the strength to lift the gun, and an ammo cabinet.
Problem dealt with.

EDIT: Changed my mind... An Imperator Titan with crew. Much more efficient.

 

[KarumaK]

My next from Armored Core: For Answer.

15,000 is more than I'm used to at target practice, should be fun.

 

[Ridonculous_Ninja]

So long as none of them had arrows, Force Push from the original Fable would keep me alive forever.

YAY CHEAPNESS!

If I should ever happen to run out of mana or they get bows, I would most definately use something like Din's Fire (energy and will are two totally different bars obviously...).

For actual weaponry weaponry, the gravity gun sounds good to me, or a TANK! Or a helicopter.

FIGHT THAT YOU MEDIEVAL JERKS!

 

[theultimateend]

Hate to ruin the stream of creative answers, but, why not just shoot them? Armor isn't bullet proof or even bullet resistant. Hell, arrows went through the suits.
Maybe a nice fixed gun, like a mounted 50.cal or an M60, with a rather large barrel to finish them all off.

That's why there is 15,000 of them!

Which is why I need a lot of ammo.
=]
It's not creative, but it works.

Not as well as you might think.

Many a machine gunner died because of the "send a million chinese farmers" strategy.

 

[SendMeNoodz84]

A butterfly knife.

I can take them.

 

[Ridonculous_Ninja]

It may not be creative, but a minigun would do nicely. Or 6, yeah 6 miniguns.... I'll be right back.

I believe 6 A10 thunder-birds gattling cannons because they own and those missles PWN and Thank you Hawx

Not to be rude, but It's thunderbolt not thunder-bird. But yes, 6 of those guns would do very nicely.

That is the Gau-8 Avenger, and it kills. Everything. You wouldn't even need 6, 1 is more than enough. If we are talking 15,000 knights from when they are at their peak, i.e. they know nothing of the modern world, then if 1 doesn't kill them all it will scare them enough after killing most of them.

Admittedly my first choice isn't a weapon as much as it is a force of nature: Toph Bei Fong, yes, the blind girl from Avatar. For an actual weapon I'd use Raging Heart from Magical Girl Lyrical Nanoha. Special note for Samus Aran's powered armor: it is a weapon and it would most certainly work here.

Watching someone screw attack through 15000 knights would be hilarious.

I would pay to watch that.

 

[Whitefeather]

I can't beleive no one has said this, Mark 19 mounted automatic 40mm grenade launcher, or a few if the barrel on one heats up too much. The ones that didn't think I was God and ran for their pathetic lives would be blown to grotesque nibblets of red mush. But if they were too close for even that I'd just replace the Mark 19's with miniguns. Not original with that but it'd do the job, don't you think?

 

[HellRaid]

I use Orbital Bombardment.

 

[dududf]

Hah ! No fatman eh??!!

Experimental MIRV.

Bow down to your LEEAAADER!

And if all else fails, the crotch laser from No More Heroes.

 

[Lyri]

Super Sheep.

 

[Kingsman]

Giant magnet.

There's got to be SOME game that has a giant magnet in it...

 

[Lucane]

Cole Mcgraff's Lightning powers from inFAMOUS.

Last time I checked metal is conductive and I could like a corpse to recharge while being feared for possibly being feared as a witch.(Provided it's in present time and I'm back in time when electricity isn't widespread enough to keep me from being woosy in a field.)

If super powers don't count as a weapon then I'll just take the package Mr. Mcgraff was carrying in the being of inFAMOUS which I would believe classifies as one.

Edit:

Lightning powers ala Infamous. Bet you regret wearing all that sheet metal over the entire surface area of your body now, don't you lads?

Nice ... oh Red or Blue for you? it would be considered self defense so no karma change fighting them but you'd have a previous history. Think I'd have Blue.

 

[Aur0ra145]

Napalm all the way
