Import any weapon from any game into Call of Duty

[Rule Britannia]

Ok so if you could import any weapon from any game into Call of Duty what would it be (If you know of games that have perks for example fallout or dragon age go ahead and list 3.)
(secondary weapon must be smaller than primary)

Primary
Experimental MIRV

Secondary
Protoman's sword (awwwww yeah)

Perks
Not sure of name but I know in fallout there's a perk than reduces explosive damage

 

[GundamSentinel]

Primary:
Gravity Gun

Secondary:
Portal Gun

Perks:
Do I need any perks?

 

[webzu]

Primary
BFG9000

Secondary
Link Gun from UT

Perks
Don't know?


Edit: damn, beaten to it :I

 

[Johnnyallstar]

Primary: Mighty Boot!

Secondary: Brass Knuckles

Perks: Roid Rage- You gain small amounts of health back when striking with brass knuckles or the Mighty Boot.

 

[Vampire cat]

Primary:
A Heavy Bolter from Warhammer 40,000 (present in pretty much all games of the kind). If you know a bit about the specifics of that gun you know how lethal it would be in this day and age =3. Explosive rounds!

Secondary:
Pilum H-AVR (from BF 2142). It's an AT thing, so I assume I'm allowed to take it as secondary XD. I chose it only because I love it, no other reason...

It was never said it needed to be balanced, so...

 

[Jabberwock xeno]

Primary:
Gravity Gun

Do I need any perks?

Secondary: The Moon.

 

[Saelune]

Primary: DOOM 2 Doouble Barrel Shotgun
Secondary: Halo 1 Pistol

 

[LFC Scouser]

Primary: Portal Gun

Secondary: Rico's grappling hook thing

Perk: Whatever that one from fallout that makes an explosion when you drop below 20% health

[jakko12345]

Primary
Some kind of gun that actually kills the whiny 12 year old at the other end rather than the Russians I've been told are evil

Secondary
GAU-8 avenger cannon for the lulz

Perks
Erm, i don't really know any

 

[Coaxill]

Primary:
Fallout 2 pulse rifle
A gun that doesn't use projectiles. When the trigger is pulled, the target is jolted to death with thousands of amps of electricity.
Secondary:
Infinity edge (League of Legends)
Simply by having this item in my inventory my crit chance with the pulse rifle would be brought to 100%, and would also increase the crit damage of an already devastating weapon.

Perks:
Bloody mess, steady aim, and a bag of sour Skittles

A gun that shoots shurikens and lightning.

Thats all i need.

Secondary: Thori'dal, the Stars' Fury

Perks: I don't think I need any perks for this combo.

 

[Derek_the_Dodo]

Primary: Sentinel (Nightfire)

Secondary: Mage's staff of paralysis (Oblivion)

Perks: Jetpack from Halo Reach. Because Jetpacks make everything cooler.
