Unlock
Railguns and the Impactor ships that carry them are unlocked by Accelerator Amplification.
Use Notes
More information on these weapons can be found on the Impactor page.
Upgrades
Railguns recieve 50% more mass and damage from Neutronium Rounds and 20% faster refire from VRF Technology. The 10% damage bonus from Accelerator Amplification is factored into base damage below because you cannot have Railguns without it.
Counters
Railguns will ricochet off of ships with one of the four armors, but ricochets will still impart kinetic force. All Railgun damage will be completely negated by Grav Shields, and Shield Projectors. Deflectors should not affect Impactors.

The "C" in D/C and DPC/C is Command Points. It costs 6 C to field a Cruiser and 18 to field a Dreadnought.
Humans, Tarka and Hivers will see no difference in damage between 3 CR and 1 DN Impactors. Morrigi and Zuul will get more Railgun damage from 3 CR than 1 DN, but a Zuul Impactor DN is a competent close range fighter. The Liir will see more damage from 1 DN Impactor compared to 3 CR Impactors.
