AN 94 multi-pap'd attachments: red dot sight, target finder, grip, MMS
PDW 57 - red dot sight, target finder, ??? Never pap'd it more than that. 50/350 ammo
SVU - can't pap more than once
Trample steam build able - pump/motor, metal grate, flag, whoopy cushion thing (not to sure on the name)
There's 4 spawn points in the starting room and 4 spawn points passed the first 750 door on the first level.
Sliquifier - 3 spawn points in the build able room. One spawn directly above the build table by the couch. 2 in the power room by the switch. 1 right outside the power room by the water heater.
This is all I can think off of the top of my head. Sorry for the bad editing but I'm using my phone while at work so my post is a little rough.
