you find them.

From what I've found so far, you can make the knife gloves by finding gloves near the fire tunnel where a shield part may spawn, and you can find a knife in between generator 3 and the living quarters or something like that. I also found the weird guns on gloves by finding what looks like an M16 near the lightning staff piece that is by gen 3, and the glove at the lightning staff piece that's in the church. No idea about anthing else yet.
Edit : Found the bow for the "blambow" in the wind tunnel on a corpse, and the wood part or something under the church near the tank or at generator 6. Also found a part of the toma haxes up at the tank station near generator 2, where Thor steps and a shield piece may spawn, completely forgot where I found the other part

Anyone got the vpr yet?

so where exactly is the parts? only found all for the gun-gloves and tomahawks.
