'Pulse Pack' is a standalone mod wich adds a new Railgun and a exclusive turret with new mechanics, it shoots a mid to long range laser that penetrates through anything, including you and your buildings! It has a very narrow coverage area, just like artillery towers, it must be protected from enemies that get too close, its best used at critical choke points. it has been balanced to be played with vanilla factorio.
also the graphics has been made with whatever i've found in the junkyard from my base, eventually better mod suport will be added.
It has its own technology supposed to be unlocked slightly after laser turrets, but it a bit more expensive, it also shares the same upgrade as lasers.
