Valve said there would be 10 weapons in the game, so far I have only seen these:
1.M16
2.Uzi
3.12 Guage pump action shotty (probably a civilian Mossberg 500)
4.M14 With scope
5.Colt 1911 pistol
6.M1014 semi auto shotty
What else will there be?

a high powered machine fed proton cannon

Surely there must be a crowbar.

No need for a crowbar, you can just bash the zombies with a rifle butt or your fists.

...lol i said butt.

a 28 guage shoulder mounted semi-automatic nuclear powered plasma rifle with electron microscope attachment just so you can vaporize the small instead of the far.

My bet is there will be a chaingun somewhere and there's gotta some kind of melee weapon

I think that's it save the possibilty of a magnum revolver.

okayyyyy.............

On a more serious note, anyone else counting on an AK?

Again, the melee is the butt of the gun or your fists.

...lol i said butt again.

But what if your path is blocked by a large wooden crate?

*shudders*

I guess an AK-47, either a Deagle or the 357, a hunting rifle, and an MP5.

I doubt there will be a chain gun, I just can't imagine survivors of a zombie outbreak wielding one of those.

yeah but I mean like a sword or something

Probably an AK, or maybe a revolver.
CHAINSAW! I wish.

Maybe not a chaingun but I have seen gameplay with a mounted machine gun.

A machete

Chainsaw?
BFG 9000?
Cerebral bore?
Gravity Gun?
Lancer?
Barret M105 .50 caliber sniper rifle?

I dunno. You might just have to wait until the game comes out. (Fingers crossed for the cerebral bore)

I hope they include a gun that shoots out lightning and shurikens, that would be fucking awesome. (lol)

I'd like a large array of improvised blunt weapons. Tonnes of crowbars and whatnot.

That might be a little too much to ask for, though.

Wait...how about a grenade launcher? some kind of heavy weapon...they already have molotovs and pipe bombs (don't fuck with those-they will kill you and your teammates) because otherwise the tanks will be impossible to kill.

And a stylized shotgun, not the one from HL2

Portal gun.
