Hello visitor! A note about the contents of this wiki: Barotrauma is a game with several years' worth history as a free-download open source game, and this wiki has been written primarily based on this legacy version. As such, not all content is relevant to the Steam release. So please wait patiently as the contents are updated, and feel free to contribute new information once the Steam version of Barotrauma is released!
Hello there! We are conducting a survey to better understand the user experience in making a first edit. If you have ever made an edit on Gamepedia, please fill out the survey. Thank you!

The railgun is a stationary weapon in Barotrauma. It is technically composed of three installations: the railgun proper (which itself is made up of the base and barrel), the railgun controller, and the railgun loader.
Function[edit | edit source]
The railgun uses railgun shells as ammunition. Those must be loaded by hand in the railgun loader; up to 6 shells can be loaded at a time. The usual railgun shells are hollow and can be filled with an item. This feature allows for the placement of explosives (for example a C-4 Block) inside, creating more damaging munitions if need be. Nuclear Railgun Shells are special ammunitions of extreme destructive power, which can be precious to bring down some creatures, such as a Moloch or a Charybdis. Due to the large radius of the ensuing explosion, it is however highly recommended to use this type of ammunition at a distance.
The best railgun ammunition comes in the form of the Ancient Weapon, which is incredibly rare. While the damage it does against Creatures is the same as the Nuclear Railgun Shell, the resulting explosion does five times more damage against structures than the Nuclear Railgun Shell, making it ideal for submarine VS submarine combat.
A railgun loader must be connected to one or more railguns proper in the submarine editor, it can not be connected outside of the editor. A railgun controller is connected to one or more railguns proper with wiring through their respective connection panels. Both the railgun controller and the railgun proper require power to function; however, the railgun loader does not require any power. A railgun proper requires a supercapacitor, which needs to be charged before firing, and each shot will use up some amount of this store to function as its power supply in order to be able to fire. Connecting the railgun proper directly to the power network will leave it unable to fire. Note that attempting to fire a railgun with no shell loaded doesn't empty the capacitor.
The railgun proper, when edited in the submarine editor, is given a pair of numbers under RotationLimits formatted thus: 0,180. These numbers are angles that describe the limits that the railgun proper can be rotated when aiming. A railgun proper with the RotationLimits set at 0,180 will be able to rotate from the right down and around to the left. A railgun proper with its RotationLimits set at 180,360, contrastingly, will be able to rotate from the left up and around to the right.
Usage[edit | edit source]
To use a railgun, the character must be positioned in front of a railgun controller and, when the railgun controller is highlighted, click 'e' on the keyboard. The railgun(s) proper can then be aimed while holding the right mouse button, and fired, using a shell loaded in the associated railgun loader(s), by clicking the left mouse button.
