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

[Hokutan]

A Heavy Bolter

 

[monkey_man]

a wall made of pure energy coming from the knights themselves . hehe cant touch me ooh and it power my highly overpowerd pc with an 50 inc screen and capable of playing ANY game (even console ones) and when they are all dead from me playing too much ill sell all of the armour suits the nuts wore and make millions! hehe i always win knights

 

[Lazy Kitty]

Developer console.

 

[Jerich0]

BFG

 

[Cherry Cola]

Spoiler: One word: Pandora

^ That a million times

Or Nazi zombies

 

[Rusty Bucket]

Wait. Fuck. I take back my post of the Warthog from Halo. That was so short sighted of me.

Spoiler: THE MONKEY LORD

Yeah. See those trees looking TINY? See that insane laser that cuts through giant robots of doom? Yeah. 15,000 knights go down in a blink.

Pah, that thing's tiny.

Spoiler: Note the teensy little Monkeylord to the left

Not to mention that the Megalith can lay eggs containing bricks (the boxes on legs just in front).

Man, I've only played the demo. I'm missing out on so much awesome!

The Megalith is in Forged Alliance, the expansion pack. It's well worth investing in if you like RTS's and have a computer capable of running the damn thing. It's a huge CPU whore.

But yes, you are definitely missing out on awesome.

1. Take a predator box (it's not a weapon mind you) and place it on the bottom of a cliff.
2. Use the portal gun to open a portal above and below you.
3. Your now traveling at terminal velocity. Violia, you are now the weapon.
4. If your worried about the bone shattering impact of you and knight, then open a portal below the knight and above his fellow knight. The box will protect you from any weapon they have, while they act as your high velocity weapon.

If that doesn't work I'll just ride a Shai-Hulud. Cookie for reference

But I thought Shai-Hulud only resided in the desert sands of Arrakis?

I would use a Star Trek comm badge and the words, "One to beam up. Energize!"

Those words have saved countless lives on TV and in some video games. Why would I try and fight 15,000 heavily armored, fully trained knights? It would be an uphill battle that I would eventually lose; no matter what weapon I chose (well, hand-held weapon anyway).

-snip-

I will see your Megalith and raise you one of these!

Spoiler: Seraphim Experimental Bomber

That thing is a win button if your opponent has no anti-air defenses, and I doubt knights with swords and arrows would have a snowball's chance in hell against one.

 

[tehweave]

BFG 9000. Simple.

 

[SenseOfTumour]

I'd have to choose again from Armed and Dangerous, the Topsy Turvy bomb.

simply drives itself into the ground, pops a hook out for you to hold onto, then flips the whole world upside down (which obviously can't happen, but I don't care - I guess it's reversing gravity really, but it looks more like an upside down moment when you're hanging by one hand from your new ceiling.)

Then 5 seconds later, the world is raining crunchy meat filled tin cans.

Or the Painkiller electrodriver, any lightning gun, combined with men running at me in full metal armour, should be amusing!

 

[slackbheep]

Do tanks count as weapons?

 

[HannesPascal]

Maybe Magneto even though he's not really a video game weapon but still.

 

[Mad Maniac with axe-firing chainsaw]

A white flag...

I can actually think of a whole raft of world-ending ones. Meteors, summons from final fantasy, Cthulhu summons, spells from The Big Book Of Doom, legendary Pokemon... and a tank. Yes, a tank. Just imagine the chaos that one single Challenger II tank would cause for a medieval army.

 

[NeutralMunchHotel]

Godot's Cup of Coffee.

 

[Jeffronian]

I'd have to go the Scribblenauts route and summon Cthulhu!

 

[AVATAR_RAGE]

the power of GOD!
