Stealth Approach: The Diamond — Payday 2 Guide

Stealth Approach: The Diamond

The Diamond heist in Payday 2 presents a unique and intricate stealth challenge, demanding meticulous planning, precise execution, and excellent team coordination. Unlike many other stealth heists, The Diamond emphasizes environmental puzzles and security system manipulation over pure guard elimination. Success hinges on navigating a high-tech museum, bypassing sophisticated laser grids, disarming pressure plates, and ultimately accessing the priceless Diamond without triggering a single alarm.

Recommended Loadout & Skills

For a successful stealth run on The Diamond, a well-rounded team with specific skill sets is crucial. Consider the following:

• Ghost Tree (Shinobi, Artful Dodger): Essential for faster lockpicking, quieter movement, and increased bag carrying speed. Skills like ECM Overdrive (to open certain doors) and ECM Specialist (for extended ECM duration) are invaluable.
• Fugitive Tree (Revenant, Brawler): While less critical for pure stealth, skills like Nine Lives (Aced) can provide a safety net in case of a mistake.
• Mastermind Tree (Controller, Sharpshooter): Dominator (Aced) and Joker can help manage guards if a situation arises, though minimizing guard interaction is ideal. Inspire (Aced) is always a strong utility skill.
• Technician Tree (Engineer, Breacher): Drill Sergeant (Aced) can speed up certain drills, though most of The Diamond's challenges are not drill-based.

Essential Equipment:

• ECM Jammers: Crucial for opening certain doors, delaying alarms, and interacting with specific security systems. At least two ECMs per player are recommended.
• Body Bags: For disposing of any guards you absolutely must take down.
• Trip Mines (Sensor Mode): Excellent for marking guard patrols and identifying blind spots.
• Camera Loop: A valuable asset for temporarily disabling cameras in critical areas.

Phase 1: Initial Infiltration & Exterior Security

Upon spawning, your primary objective is to gain access to the museum's interior. This typically involves:

1. Scouting the Perimeter: Identify guard patrols outside the museum. There are usually 2-3 guards patrolling the exterior grounds. Use your camera feed (if available) or trip mines to mark their routes.
2. Finding the Keycard: A keycard is required to open the main entrance or a side door. This keycard is often found on one of the exterior guards. Silently take down and bag the guard carrying the keycard. Alternatively, a keycard may sometimes spawn on a bench or table near the entrance.
3. Disabling Exterior Cameras: There are several cameras positioned around the museum's exterior. Use your Camera Loop skill or ECMs to temporarily disable them as you move.
4. Gaining Entry: Use the acquired keycard to open one of the main doors. Be mindful of any interior cameras that might immediately detect you upon entry.

Phase 2: Navigating the Museum's Interior

Once inside, the real challenge begins. The museum is a labyrinth of security measures.

Guard Management & Camera Systems

The Diamond features a unique guard system. While there are standard patrolling guards, the museum also employs a significant number of stationary guards and security personnel in control rooms. Unlike other heists where you might clear out all guards, The Diamond often requires you to bypass them entirely.

• Standard Guards: Patrol predictable routes. Use sensor trip mines to track them. Avoid confrontation where possible.
• Stationary Guards: Often positioned in corners or near exhibits. These guards have limited vision cones but are difficult to bypass without careful timing.
• Security Rooms: There are multiple security rooms throughout the museum. Each room contains a security monitor. Disabling all monitors will disable all cameras in the museum permanently. However, this often requires keycards or ECMs to access.
• Camera Placement: Cameras are ubiquitous. They are often placed at choke points, above doorways, and in large exhibit halls. Prioritize using Camera Loop or ECMs to bypass them.

Laser Grids & Pressure Plates

These are the primary environmental hazards in The Diamond. They are often found in corridors leading to high-value exhibits or the Diamond vault itself.

• Laser Grids: These are visible red laser beams. Touching them triggers an immediate alarm.
  • Navigation: Most laser grids have small gaps or patterns that allow careful players to walk or crouch through. Observe the pattern and timing.
  • Disabling: Some laser grids can be temporarily disabled by interacting with a nearby control panel. This often requires a keycard or an ECM.
  • Common Solution: Look for floor panels or wall panels that can be interacted with. Sometimes, a specific sequence of interactions is required.
• Pressure Plates: These are floor panels that, when stepped on, trigger an alarm. They are often hidden or blend into the floor.
  • Identification: Look for subtle discoloration or slight elevation differences on the floor. Use your stealth outline (default 'Q') to highlight interactive elements, as pressure plates sometimes have a faint outline.
  • Bypassing: The most common method is to jump over them. This requires precise timing and positioning. Alternatively, some pressure plates can be disarmed by interacting with a nearby control panel, similar to laser grids.
  • Teamwork: One player can often "bait" a pressure plate while another interacts with a disarm panel, or simply guide teammates through safe paths.

Phase 3: The Diamond Display Case & Laser Puzzle

The ultimate goal is to access the Diamond itself, which is housed in a heavily secured display case. This involves a multi-stage puzzle.

Finding the Keycards

To access the Diamond's inner sanctum and manipulate the laser puzzle, you will need multiple keycards. These are typically found:

• On patrolling guards within the museum's interior.
• In security offices or staff rooms, often on desks or in lockers.
• Sometimes in less obvious locations, such as behind paintings or under specific exhibits.

Strategy: Systematically clear out accessible rooms, prioritize taking down guards in isolated areas, and always check every interactive object.

The Laser Alignment Puzzle

The Diamond's display case is protected by a complex laser system that must be aligned correctly. This is the "puzzle element" mentioned previously.

1. Locate the Control Panels: There are usually 3-4 control panels located around the Diamond display case room, or in adjacent rooms. These panels control the direction and intensity of the lasers.
2. Identify the Target Pattern: On the floor or wall near the Diamond, there will be a visual representation of the correct laser alignment pattern. This pattern is randomized each heist. It might show specific laser colors intersecting at certain points, or a numerical sequence.
3. Manipulate the Lasers: Each control panel will have buttons or levers that rotate or adjust the lasers.
   • Rotation: Some panels rotate a specific laser beam clockwise or counter-clockwise.
   • Color/Intensity: Other panels might change the color or intensity of a laser, which needs to match the target pattern.
   • Team Coordination: This puzzle often requires multiple players to interact with different panels simultaneously, or one player to guide others. Clear communication is paramount. "Player A, rotate the blue laser left. Player B, adjust the green laser's intensity."
4. Trial and Error (Careful!): Incorrect alignment will trigger alarms. Proceed cautiously. If a laser turns red or a warning sound plays, immediately stop and re-evaluate.
5. Final Alignment: Once all lasers are correctly aligned according to the target pattern, the display case will unlock, allowing you to grab The Diamond.

Phase 4: Securing the Diamond & Escape

Once The Diamond is secured, the escape route will be revealed. This typically involves backtracking through the museum, or sometimes a new exit opens up.

• Bagging The Diamond: The Diamond is a single, heavy bag. Designate a player with high bag-carrying speed (e.g., Ghost skills) to transport it.
• Escape Route: The escape vehicle will usually be waiting outside the main entrance or a side alley. Be prepared for any remaining exterior guards or cameras.
• Final Dash: If an alarm is accidentally triggered during the escape, be ready to fight your way out, but ideally, maintain stealth until the very end.

Common Pitfalls & Tips

• Rushing: The Diamond punishes impatience. Take your time, observe guard patterns, and plan your moves.
• Ignoring Cameras: Cameras are everywhere. Always assume you are being watched and plan accordingly.
• Solo Attempts: While possible, The Diamond is significantly easier with a coordinated team, especially for the laser puzzle.
• Lack of Keycards: Prioritize finding keycards. They are essential for progression.
• Miscommunication: For the laser puzzle and navigating complex areas, clear and concise communication is vital. Use callouts for guard positions, camera angles, and puzzle steps.
• Don't Forget the Side Loot: While The Diamond is the main objective, there are often valuable artifacts and cash piles in display cases throughout the museum. If time and safety permit, grab these for extra cash and XP.

By following these detailed steps and strategies, you and your crew will be well-equipped to conquer The Diamond in stealth, securing one of Payday 2's most iconic and challenging treasures.
