The SPAS-15 semi-automatic shotgun looks and fires more like an assault rifle than a traditional shotgun. It delivers bursts of deadly shot at a devastating pace. The SPAS-15 has both semi-automatic and pump action functionality.
It is chambered for 12 gauge shotgun ammunition, and has a magazine capacity of 6 rounds. The box magazine allows for much faster reloading. It is capable of both fully-automatic fire or manual pump action shots for more accuracy and less muzzle climb.
- In third person, the player holds and reloads the Jaegerspas XV the same way they do with the Utica M37.
- The secondary firing mode is unrealistic, since it is usually reserved for low-pressure ammunition that doesn't exert enough force to cycle the gun's mechanism by itself (such as less-lethal beanbag rounds), and no such ammunition is available in the original game.
- The name "Jaegerspas" can be understood in German as "hunter's fun".
