This is an immensely devastating version of the standard Disruptor Gun. Again it is based on the same inter-dimensional technology that seems to power the Dimension Gates. It is possible that these weapons are actually drawing power from some remote source connected by an inter-dimensional field. This amazing technology seems to be incongruous with the Aliens' organic weaponry and may originate from some other Alien intelligence.
The alien's proper handheld offensive weapon. Everything that really matters is improved compared to the Disruptor Gun. A large and heavy beam weapon doing more damage at longer range with better accuracy. Fire rate is slightly slower but is offset by larger energy (ammunition) stores. A dual wielded setup may be preferrable for increased fire rate at the expense of lower accuracy. A strong and accurate X-Com agent is best.
This weapon will become the mainstay of Anthropods and Skeletoids. Weapon shortages will not be a problem. Manufacture of these is exotic items is not necessary. Does not detonate Poppers.
Which is better?
Toxigun or Devastator Cannon
