Railgun

The Railgun is a weapon that is very powerful and rare. It's similar to the Shotgun, but it can kill multiple people in its broad range of fire and it only be shot 5 times, just 1 below the shotgun. It's located in the Lab in Dangerous Weapons, which you can buy it for 500 money. It can only be accessed by a player with the Administrator Keycard, and it's rare to see someone shoot it or even wield it. It is the second most expensive weapon, only losing to the Infinity Gauntlet, which is for $800.
