Railway Rifle (Fallout 3)

The Railway Rifle is a custom-built weapon, made from a crutch that comprises the stock and grip part of the gun, a Pressure Cooker that acts as a firing chamber, a Fission Battery that acts as the firing pin and a Steam Gauge Assembly that comprises the grip, ammo storage and barrel of the gun.

Characteristics

 * The Railway Rifle falls into the Small Guns category.
 * The gun fires Railway Spikes. Though only moderately damaging, it is very effective at dealing limb damage (due to a 3x limb damage multiplier), able to cripple limbs often with just one shot. On the killing shot, a spike may tear off the struck limb or head, and possibly pin it to a fixed object, for example wall or the floor.
 * The Railway Rifle has a deceptively low DAM stat, and has moderate accuracy (better than the assault rifle, lower than the hunting rifle). However, its projectiles have much more mass than bullets, making it more effective at short to medium ranges, and most effective in V.A.T.S. where its limb-destroying effects can be put to precision use. It has a high critical multiplier stat that, depending on your base critical chance, may make the Railway Rifle one of the best non unique Small Guns.
 * The stock of the Railway Rifle seems to be an actual weapon stock, similar to that of a combat shotgun, instead of appearing as a crutch like the schematics intended. The hand grip of the crutch can still be clearly seen under the barrel section attached to the piston.
 * The Railway Rifle is one of two weapons best for crippling someone's limbs in or out of V.A.T.S. The only other weapon is the Dart Gun. (The Dart Gun cripples legs)
 * After being fired, it makes the sound of a steam whistle.
 * Despite the supposed solidity of the spikes, nothing can be placed on top of them. For example, if two spikes are lodged in a wall at roughly the same height, you are unable to place something on top of them.
