Gattling Rail Mk 1 is a weapon from Shields-Up.
Level Requirement: 7
The rail gun is a nasty weapon, first used as a planetary defense system and later modified for onboard vessel use. The Gattling variety, as its name suggests, is a high ROF - "rate of fire" weapon.
You will require Kinetic Weapon Skill level 60 to use this weapon. It will also require expert calibration and fitting.
The Gattling version is normally extremely effective at passing massive amounts of kinetic energy projectiles "through" an enemy shields. Imagine being hit by a 1000 rounds per second and you get some idea of the destructive power of this gun.
The energy requirements for this gun are lower than would be expected, but the output is substantially lower than say a large beam weapon or a particle beam.
