I love this mod. I'm probably missing the point of the railgun, as it seems to have the same stats as the Triple Cannon Turret. Maybe it'll work better if it's changed from a beam weapon to something that fires an extremely fast bullet, with large penetration? After all, real railguns aren't beam weapons, and there is already a plasma beam turret in the mods to fill the role of targetable beam weapon.
Keep up the good work! I hope to see the Tokamak active soon. I'll look forward for a new resource for all plasma-tier weapons, hopefully with their own more explody generator.
