What it's for
It fires faster than the Thompson and holds 30 pistol rounds, so up close it dumps damage in a hurry. The downsides are real: lower per-shot damage (60 head), medium recoil, and heavy bullet drop that makes it unreliable past short range.
How to use it
- Push corners and interiors — it wins the first half-second of a close fight.
- Don't engage in the open; the drop and spread waste your mag.
- Pair it with a shotgun or a Python for when a target backs off.
Bottom line
A specialist. Inside a base or compound it's excellent; in the open it loses to almost anything. Bring it where fights are short.
