Railgun is a weapon that first entered the Quake series with Quake 2. It can be picked up on any map.
INFO
The Railgun rewards precision with high damage, and punishes carelessness with a long reload time. Do not use the Railgun in close combat, unless you are positive of the outcome, as missing will leave you useless while the gun cools down. Deny your opponents crucial armor and powerups by taking aim from a distance with minimal chance of retribution.
A Quake 2 Railgun skin is obtainable via loot boxes, shards or hard currency.
