Flak Cannon

The Flak Cannon is a staple of the Unreal series and has been in the game since the very beginning. In general, the primary fire launches flak shell shards, and the secondary fire launches a flak shell bomb. The primary differences between the Flak Cannon's incarnations are the damage it causes, the number of times the flak shards bounce, and the distance the flak bomb flies.

''Trident Defensive Technologies Series 7 Flechette Cannon has been taken to the next step in evolution with the production of the Mk3 “Negotiator.” The ionized flechettes are capable of delivering second- and third-degree burns to organic tissue and cauterizing the wound instantly. Payload delivery is achieved via one of two methods: ionized flechettes launched in a spread pattern directly from the barrel; or via fragmentation grenades that explode on impact, radiating flechettes in all directions.''
