Unreal Tournament 2004
''The Schultz-Metzger T23-A 23mm rotary cannon is capable of firing both high-velocity caseless ammunition and cased rounds. With an unloaded weight of only 8 kilograms, the T23 is portable and maneuverable, easily worn across the back when employing the optional carrying strap. The T23-A is the rotary cannon of choice for the discerning soldier.''

Unreal Tournament 3
Taking some hints from Unreal's Stinger weapon, the new Stinger Minigun has a powerful instant-hit primary fire, while the tarydium shard firing alternate fire mode can nail corpses to a wall.
