Stinger

The Stinger is a weapon found in Unreal and UC2. A similar version is also seen in Unreal Tournament 3. It was originally designed to be a mining tool by the Liandri Mining Corporation. The Stinger launches small tarydium shards to carve away unwanted rock. It was discovered to be a decent weapon, and put into military use.

Unreal Tournament 3 features a weapon called Stinger Minigun that is a hybrid of a Stinger and a Minigun.

The Stinger's regular fire mode does relatively low damage. The alternate fire mode shoots a spread of tarydium shards, shotgun-style, doing medium damage at close range.

UC2's Stinger is similar to that of Unreal, but has some added features. Holding down the trigger of the primary fire mode for a while causes the weapons fire to do more damage. The alternate fire mode launches shards to have limited homing capabilities. Like all UC2 weapons the Stinger does not have unique ammo, but uses the Energy Ammo type.

''The Stinger is a Liandri mining tool that fires shards of Tarydium crystal at an alarming rate. Continuous fire causes overheating, leading to a catalytic process that makes the shards even more deadly. The alternate fire shoots larger, semi-sapient shards that will veer towards a locked-on opponent.''
