While GTA III's combat system is relatively simple, mastering a few advanced techniques can significantly improve your survivability and efficiency in firefights. Don't just stand and shoot; utilize your environment and weapon strengths to your advantage.

- The Drive-By Master: The Uzi and MP5 are your best friends for drive-bys. Learn to aim effectively while driving to clear out enemy vehicles or groups of pedestrians quickly. This is often safer than engaging on foot.
- Explosive Entrances/Exits: Use grenades or Molotovs to clear out areas before entering, or to create a diversion for a quick escape. A well-placed explosive can turn the tide of a difficult encounter.
- Sniper's Perch: For missions requiring you to eliminate targets from a distance, find a high vantage point with a clear line of sight. The Sniper Rifle is invaluable for these situations, allowing you to take out enemies before they even know you're there.
- Vehicle as Cover: Your car isn't just for driving; it's a mobile shield. Use it for cover during shootouts, especially against multiple enemies. Just be mindful of its health, as it can explode if too damaged.
- Target Prioritization: In a chaotic shootout, always prioritize enemies with powerful weapons (shotguns, assault rifles) or those who pose the most immediate threat. Eliminating them first will reduce incoming damage.
- The 'Strafe and Shoot' Maneuver: While not as fluid as later GTA games, you can still strafe (move sideways) while aiming. This allows you to dodge incoming fire while maintaining your aim, making you a harder target.
Practice these techniques in free roam to become a more formidable force in Liberty City. The more comfortable you are with these tactics, the easier challenging missions will become.
