Switch to Weapons That Fit the Situation
When you first start the game, your weapon wheel will only allow for two weapons, which consist of at least one pistol and whatever else you can find. As you progress through Mafia III, though, you’ll be able to carry even more gear as you explore New Bordeaux. Once you’re able to, make sure that you bring something for each different type of situation. Sniper rifles for ranged encounters, assault rifles and machine guns for large groups, and shotguns for up close and messy kills.
You can switch as a fight changes as well. Not all encounters stay the same throughout. You’ll often start from far, only to find that you’re surrounded and need to switch to something that can deal with nearby foes quickly and efficiently. Always make sure you have the right tool for the job.
