Pistol
The most common firearm. Low recoil, decent accuracy, and a moderate rate of fire. Excellent for headshots and quick eliminations. Ammo is limited, so make every shot count. Remember to drop the empty pistol to grab a new one.
Shotgun
Devastating at close range, capable of taking out multiple enemies with a single blast. Very slow reload (requires pumping action) and limited range. Best used for clearing tight spaces or when enemies are grouped together.
Rifle
Longer range and higher accuracy than the pistol, but often has a slower rate of fire. Good for picking off distant targets. Can be unwieldy in close quarters. Use it to control sightlines and eliminate threats before they get too close.
