Notes
- Dreamwave' More than Meets the Eye profiles often switched up the names of weapons, sometimes just a little—such as adding the word "rifle" to the end of an existing weapon's name—and sometimes by substituting a completely different-sounding weapon entirely. The pulse cannon is an edge case; it may have been intended as a genericised upgrade to Groundbreaker's pulse blaster and/or Broadside's plasma-pulse gun, or it may have been created as a new weapon type intended to replace them both.
