*Overcharging increases damage and armor penetration by up to 50%.

Tactical Information

  • The level of destruction the weapon projects is based on charge rate upon firing, able to decapitate and destroy most light or medium targets easily.
  • Additionally the weapon can be taken off Safe Mode, allowing it to overcharge and potentially fire an even more deadly shot which can blow apart most foes or rip chunks of armor off heavy units.
    • This must be done with caution, however; Safe Mode prevents the weapon from experiencing a catastrophic malfunction. If the charge level exceeds maximum, the weapon will violently tear itself and its wielder apart in an explosion.
    • Overcharging increases total damage and armor penetration by up to 50%, scaling linearly through the overcharge process.
  • The weapon has reduced effectiveness against enemies with high durability such as the head of Bile Titans or the thrusters of Gunships, requiring additional shots compared to weapons with comparable durable damage.[1]
  • The weapon can also be used to effectively engage Chargers by targeting their forelegs. Two fully charged unsafe shots from the Railgun can break the Charger's leg armor, exposing the vulnerable flesh underneath and allows it to be finished off easily with small arms fire.
    • Alternatively, three fully charged unsafe headshots will kill a Charger.
  • Against Bile Spewers and Nursing Spewers however, it's best to aim for the head as the spewer's abdomen can absorb an impressive amount of ballistic damage due to it being a squishy enemy part.
