My newest expreiment is implenting some different types of ammunition you can buy in the armory.
Currently there are only multiple ammo types for the pump-action shotgun. There are 8:
TriBall - Fires 3 massive pellets. Long range and high recoil.
000 Buck - 9.14mm pellets. High power and recoil.
1 buck - 7.26mm pellets. Moderate range, power and recoil.
Magnum alloy 2 - 3.76mm pellets. Mid-short range, moderate power and recoil.
Steel 8 - 2.26mm pellets. Short range, high power, low recoil.
Tungsten alloy 12 - 1.3mm pellets. Very short range, very high power.
12 gauge slug - Fires a single slug bullet. Long range, moderate power, high recoil.
FRAG-12 - Exploding shotgun round. Fires 6 pellets.
