Build a freeze-gun

Build a freeze-gun was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is located in B.O.M.B.-001.

Walkthrough
A bit of investigating in the Maintenance Room will turn up a schematic of a prototype freeze gun which the PC can use to assemble a gun. However, not all the parts for the gun are available in the Maintenance Room, so the PC will need to find viable substitutes for the components. Needed components are; freezer coils (kitchen); water and containers (bathroom); crushed crystal (TV in rec. room); power source (S.O.R.-1000 Beta of Delta). The remainder parts are in the Maintenance room. Once assembled, the gun works great against most armors since if super-freezes joints and moving parts, so the gun is effective against robots as well as the NCR guys. The gun will not necessarily kill a foe, but it will render it immobile for 1 to 2 rounds, giving the player uncontested turns against the crippled enemy. Assembly takes 20 minutes of in-game time.
