The descriptions are too short on the "Chain Gun" wapons, and I think the Solaris and Purple Goddess doesn't says what kind of weapon it is. (Eco = Tachyon, Wildfire = Particle, Purple = ?, Solaris = ?)
PS: Aren't those damages too high? (Since you're having an awesome fire rate, would require less accurancy, I think this is the same principle why faster fire rate weapons do less damage?)
Also, information where to buy Manta or Hammerhead is missing in the readme;)
