HWP weapon items are:
* Harpoon Cannon (not as good as the standard one, 16 rounds since it has a carriage of 4 tube packs as shown that simply rotates)
* Micro Cannon (faster firing auto cannon with 50 capacity, but only uses AP rounds)
* Recoilless Rifle (heavy cannon with HE ammo and holds twenty)
* Missile Cannon (fires same ammo as the craft gas cannon, for the displacer only, is capable of punching a hole in a USO on a lucky shot but only holds 12 rounds, so despite the power its not a replacement for the PWT or Sonic version).
* Blank Template
Some of them were borrowed from other things.
