Ranking System & Rewards — Metal Gear Solid 4: Guns of the Patriots Guide

Ranking System & Rewards

Achieving the coveted "Big Boss" emblem in Metal Gear Solid 4: Guns of the Patriots is the ultimate test of skill, patience, and strategic mastery. This section will guide you through the meticulous requirements for each emblem, focusing on the highly sought-after "Big Boss" rank and the invaluable rewards you'll unlock for your efforts.

Emblem Requirements Overview

Your performance across various metrics determines the emblem you receive at the end of each playthrough. These metrics are cumulative across all five acts:

• Play Time: The total time taken to complete the game. For Big Boss, aim for under 5 hours.
• Alerts: The number of times you trigger an alert phase. Zero alerts are crucial for top ranks.
• Kills: The total number of enemies killed. For Big Boss, this must be zero.
• Continues: The number of times you use a continue after dying. Zero continues are mandatory for Big Boss.
• Retries: The number of times you restart from a checkpoint. Zero retries are mandatory for Big Boss.
• Heals: The number of times you use healing items (e.g., Noodles, Regain, Syringes). Minimize these for higher ranks; zero is ideal for Big Boss.
• Damage Taken: The total amount of damage Snake sustains. Keep this as low as possible.
• Weapon Type: The types of weapons used. Non-lethal is key for Big Boss.
• Special Actions: Specific actions like CQC takedowns, headshots, or finding specific items.

The Path to Big Boss

The "Big Boss" emblem is the most challenging to acquire, demanding near-perfection. Here's a detailed breakdown of the requirements and strategies:

• Difficulty: Must be played on "The Boss" difficulty.
• Play Time: Under 5 hours. This requires skipping all cutscenes (press Start, then X) and moving efficiently.
• Alerts: 0 Alerts. This is paramount. If an alert is triggered, you must immediately restart from your last save.
• Kills: 0 Kills. Use only non-lethal weapons like the M870 Custom (shotgun with rubber slugs), Mosin Nagant, or the Tranq Gun (Mk. 2 Pistol). CQC takedowns are your best friend.
• Continues: 0 Continues. If you die, reload your last save.
• Retries: 0 Retries. If you hit "Retry" from the pause menu, it counts against you. Always reload a save.
• Heals: 0 Heals. Avoid taking damage at all costs. Utilize the Solid Eye's night vision and thermal modes to spot enemies and traps.
• Damage Taken: As low as possible. Ideally, zero.
• Save Count: 25 or fewer saves. Save strategically, especially before challenging sections or boss fights.

Strategic Walkthrough for Big Boss

To achieve the Big Boss rank, meticulous planning and execution are essential. Here are some actionable steps:

1. Preparation is Key:
   • New Game+: Start a New Game+ playthrough after completing the game once to unlock the Bandana (infinite ammo) and Stealth Camouflage. While these items negate the Big Boss emblem, they are invaluable for practicing routes and boss strategies on "The Boss" difficulty without the pressure of the strict requirements.
   • Initial Run: For your actual Big Boss run, you cannot use the Bandana or Stealth Camouflage. Focus on acquiring the best non-lethal weapons early. The Mk. 2 Pistol is available from the start. Purchase the Mosin Nagant from Drebin as soon as possible (Act 1).
   • Drebin Points: Accumulate Drebin Points by selling weapons you pick up or by tranquilizing enemies and selling their weapons. Prioritize purchasing the M870 Custom with rubber slugs for crowd control and the D.E. M1911 Custom for boss fights where lethal damage is unavoidable (e.g., Liquid Ocelot).
2. Act-by-Act Breakdown:
   • Act 1: Liquid Sun (Middle East)
     • Avoid Combat: Stick to the outskirts of battle zones. Use the Mk. 2 Pistol to tranquilize lone enemies.
     • Vehicle Sections: For the vehicle chase, prioritize speed and avoiding damage. Use the Mk. 2 to tranquilize enemies on motorcycles.
     • Laughing Octopus: Use the Mk. 2 Pistol to tranquilize her. Hide under the bed or in lockers. Utilize the Solid Eye's thermal mode to track her.
   • Act 2: Solid Sun (South America)
     • Jungle Navigation: Utilize CQC and the Mk. 2 Pistol. The Mosin Nagant is excellent for long-range tranquilization.
     • Raging Raven: Use the Mk. 2 Pistol or Mosin Nagant. Climb the towers and tranquilize her when she lands. Smoke grenades can help obscure her vision.
   • Act 3: Third Sun (Eastern Europe)
     • Tail Section: This is a major time sink. Memorize the patrol routes of the PMC soldiers and the Gekko. Use the Mk. 2 Pistol and CQC.
     • Crying Wolf: Use the Mk. 2 Pistol or Mosin Nagant. Utilize the snow drifts for cover and the Solid Eye's thermal mode to locate her.
   • Act 4: Twin Suns (Shadow Moses)
     • Tank Hangar: Stay hidden. Use the Mk. 2 Pistol.
     • Vamp: This is a challenging non-lethal fight. Use the Mk. 2 Pistol to tranquilize him, then quickly use a Syringe (obtained earlier in the game) on him when he's down.
     • Screaming Mantis: Use the Mk. 2 Pistol to tranquilize her. When she controls the Frogs, use the Mk. 2 to tranquilize them. When she controls the dolls, use the Syringe on the Mantis doll to break her control.
   • Act 5: Old Sun (Outer Haven)
     • Outer Haven Infiltration: Speed is crucial. Use the Mk. 2 Pistol and CQC to clear paths.
     • Liquid Ocelot (Hand-to-Hand): This fight is unavoidable. Focus on blocking and counter-attacking. Your health bar will automatically refill between rounds, so don't worry about healing items here.
3. General Tips:
   • Save Often (but not too often): Save before every major encounter or difficult section. If you make a mistake (alert, kill, damage), reload immediately. Remember the 25-save limit.
   • Skip Cutscenes: This is vital for the time requirement.
   • Use OctoCamo Effectively: Stay pressed against walls and surfaces to blend in.
   • Solid Eye: Constantly use the Solid Eye's various modes to identify threats and pick up items.
   • CQC: Master CQC takedowns for silent, non-lethal neutralization.
   • Smoke Grenades: Excellent for creating diversions or escaping tricky situations.
   • Chaff Grenades: Useful against Gekko and other electronic threats.
