Pros:

Shotgun:
Large clip
Fast firing
Pretty much an infected demolisher

Pistol:
Large clip
Fast

Cons:

Shotgun:
Not enough reserve ammo.
Fires a bit too fast to the point where i can tap and fire 2 shells
The reload is a bit buggy and can be misleading in the heat of battle.(but no points taken away.)

Pistol:
Horridly inaccurate
Uses M16 sound or customs sound for M16

Conclusion:

A pretty good mod if you feel like messing around in L4D2. But only for that really. It  would be a satisfying mod if you: Made the pistols a bit more accurate and damaging, shotgun reserve ammo was like 120 or 150, lowered the firing rate just enough to where i can tap and shoot 1 shell. And made an addon script to make the mi6 use pistol sounds or uzi sounds.
