Functionality

The Railgun fires projectiles using a charge-based mechanic, and primarily has two firing modes, Safe and Unsafe.

  • In Safe Mode, holding down the trigger builds up charge in the weapon and quickly readies a shot. While the charge is held, the player's movement is greatly reduced and releasing the trigger will immediately fire the projectile, dealing a high amount of damage. There is no inherent danger in holding a charge in Safe Mode besides the reduced movement speed, so the wielder may charge the weapon for as long as they desire.
  • In Unsafe Mode, holding down the trigger will overcharge the weapon, increasing the projectile's damage the longer the trigger is held. As with Safe Mode, movement speed is reduced for as long as charge is building up, and releasing the trigger immediately fires the weapon. Charging the weapon in Unsafe Mode can increase the damage dealt by up to 150%, causing the projectile to inflict up to 2.5 times the damage it would in Safe Mode.
    • If a charge is held for more than 3 seconds, the weapon will explode, destroying the weapon and inflicting heavy explosive damage to the wielder. The charge meter is visible on the weapon itself when aiming in first-person mode.

Tactical Information

  • The Railgun is a high-damage low-fire-rate weapon that inflicts extreme amounts of damage per shot but is limited by its low ammo capacity and the danger of self-destruction if caution is not employed while wielding it in Unsafe Mode.
    • With a total combat load of 21 rounds, it is important to make every single shot with this weapon count. Avoid using it against weak and numerous enemies, instead use it to quickly dispatch large threatening targets.
    • Movement is reduced to walking speed while the weapon is charging, in both Safe and Unsafe Mode. As this greatly increases the vulnerability of the wielder, it is important to clear the immediate area of any enemies before charging a shot, or to avoid charging the weapon for too long.
    • Because the weapon can only hold a single round at a time, it must be reloaded after every single shot. Try to get in the habit of immediately reloading after a shot, as it can be easy to lose track of its reload status when switching to a different weapon and then back to the Railgun.
  • Be wary of trying to charge the Railgun too much in Unsafe Mode, as not only will this destroy the weapon but will also inflict enough damage to outright kill the wielder.
    • The weapon emits a constant sound while charging, and in Unsafe Mode it increases in pitch as it gets closer to full charge. This is a helpful but ultimately unreliable indicator as to how much charge the weapon has built up.
    • Wearing armor with the Fortified passive halves the damage of the weapon's self-destruct when overloading, rendering the explosion survivable.
  • The primary role of the Railgun is to quickly dispatch durable high-threat targets in a single shot. For most medium-sized enemies, this can be done easily in Safe Mode, though for certain targets Unsafe Mode will be required.
