Sure, I'd be happy to provide some tips on how to handle Heist missions in Grand Theft Auto V effectively. 1. **Planning and Preparation**: Spend some time preparing. Heists require you to select crew members - your own skills and those of your crew would determine the success of the heist. Look out for the balance between skill and their cut of the reward. 2. **Listen to Lester**: Lester will usually give you two distinct ways of completing the heist: a loud, guns-blazing option, and a more subtle, stealthy approach. Listen to his guidance, it can be valuable. 3. **Practice Both Paths**: Try them out in order to understand what each consists of and to get a feel for what gameplay you prefer. You can reload your save if you're unsatisfied with the outcome. 4. **Invest in the Best Weaponry and Armor**: Before you start the Heist, invest time and resources in stockpiling the best weapons, ammunition, and armor. It's a good idea to own a bulletproof helmet and armor. 5. **Communication and Coordination**: If you're playing in a team, good communication and coordination are the keys to winning a Heist. Plan your moves in advance and ensure all team members are clear about their roles. 6. **Be Patient**: Take your time during the missions to ensure you're following the plan correctly. Rushing can lead to mistakes. 7. **Stock up on Snacks and Armor**: Always fill your inventory with snacks and armor. They can be used without going into the inventory menu, which can get you out of tricky situations. I hope this gives you a good starting point. Remember, practice makes perfect, and every failed attempt is an opportunity to learn something new. Good luck!
