RIA Trident

A weapon called the "RIA Trident" may or may not exist in. It could possibly be planned for a future update. Though not known of in the game itself, it is mentioned in a CSV file of the game's mobile version's file.

The section it appears in reads: "Advanced prototype hailed by Rubicon as the 'perfect weapon'. Each of its triple barrels employs a super powerful thermal, ballistic and chemical round." This would mean that it would be manufactured by Rubicon Industries and deal Thermal, Physical, and Chemical damage, making it an extremely unique weapon (as all other weapons are limited to a single damage type).
