By the Book

The mission 'By the Book' is a pivotal early heist in Grand Theft Auto V, requiring meticulous planning and execution. This guide will walk you through each step, from infiltrating Merryweather's headquarters to securing the target. Learn the best approaches for stealth and combat to ensure a successful outcome and maximize your rewards.

This mission kicks off the heist planning for the Union Depository. Lester calls Michael, informing him of a valuable item being held at a Merryweather facility. Your objective is to infiltrate this facility and retrieve it. The mission begins with Michael, Trevor, and Lester discussing the plan. Lester will advise a stealthy approach, but the game allows for a more aggressive strategy if you prefer. The facility is located in the Los Santos Naval Port.

Objective 1: Infiltrate the Merryweather Facility. You have two main approaches: stealth or direct assault. For stealth, you'll need to acquire a boat or swim to the docks. If going loud, prepare for heavy resistance.
Objective 2: Locate the Target. Once inside, you'll need to find the specific container holding the item. This involves navigating through guards and security systems.
Objective 3: Secure the Target. After locating the container, you'll need to extract it. This might involve a mini-game or a specific interaction.
Objective 4: Escape the Facility. Once the target is secured, you'll need to make your way out, likely facing increased enemy presence.

Stealth Strategy: The most efficient way to approach this is by using a boat. Navigate to the eastern side of the facility, where there are fewer guards patrolling the perimeter. You can then swim ashore and find an entry point. Look for areas with less visibility and use cover to your advantage. Silenced weapons are highly recommended if you plan on taking out guards quietly. The objective marker will guide you to the container.

Combat Strategy: If you opt for a direct assault, be prepared for a sificant firefight. Arm yourself with powerful assault rifles and body armor. The main entrance is heavily guarded, so consider flanking routes. Once inside, clear out enemies room by room. The target container is usually in a central area. After securing it, a getaway vehicle will be necessary. A fast car or even a helicopter can be useful for escaping the naval port.

Key Items/Vehicles: A boat (for stealth), silenced pistol (for stealth), assault rifle (for combat), body armor, and a fast getaway vehicle.

Tips for Success:

Save frequently, especially before making critical decisions.
Pay attention to the mini-map for enemy positions.
Use Lester's advice for optimal routes and strategies.
If stealth fails, don't hesitate to switch to combat.

Completing 'By the Book' successfully sets the stage for future heists and provides a substantial cash reward, making it a crucial mission for early game progression.
