The Android Railgun is a community-made weapon created by Roxxar[1], added in Version 1.32. It fires powerful rails at a slow rate of fire, it is statistically similar to the Energy Rifle and the Lite Railgun v01 CS-HShot except that the Android Railgun fires a bit slower than both, unlike the Lite Railgun however it does not need to be held in order to reload each shot.
Location
The Android Railgun does not appear in the campaign, and therefore is exclusive to custom maps created with the Advanced Level Editor.
