- In-game description.

Design details
The Heatwave fires purple hard light explosive projectiles in two different firing modes. When in the first firing mode, both sides of the front cowling are extended outward, and it fires six projectiles in a horizontal pattern. The second firing mode has the side cowlings retract inward to fire the six projectiles in a vertical diamond pattern. In both modes, the projectiles can bounce off of hard surfaces like walls and ceilings. Upon exploding, the projectiles can disintegrate organic targets, like many Promethean weapons.
