These guns are pretty damn awesome.

I didn't know if you've noticed, and have just chosen not to list it for the time being, but there's was a pump action, tube fed grenade launcher shown on a number of the e3 stage demo's. It looked like a clone of one of these:

It's under the generic name of "grenade launcher", in the pipboy menu, while the m79 inspired grenade launcher that's also used for the bestbuy preorder, is listed as a "grenade rifle". I'm still working on finding good video references, if you need them.

[edit]: you can find the china lake lookalike starting at around 3:28

Throwing Machete??? Link? That seems extremely unrealistic since machetes are poorly balanced.

for some reason all of .46acps posts arent showing up, all they say in them are "-"

You're right, it looks like they were all edited out...
