Ready or Not Three Letter Triad Mission Guide – Full Walkthrough, Secrets & S-Rank Tips

The Three Letter Triad mission in Ready or Not is one of the toughest scenarios introduced with the Dark Waters DLC. Set inside the abandoned Elysian Resort on Los Suenõs Peninsula, this mission throws players into a high-stakes operation involving heavily armed PMCs, ruthless pirates, and a critical objective that could change the city’s fate. Success here requires sharp tactics, disciplined execution, and full awareness of your surroundings.

Three Letter Triad is also one of the largest and most complex maps in the game, featuring dark halls, broken walls, and a mix of long and short sightlines that create constant CQB pressure.

Ready or Not Three Letter Triad Story and Context

The Elysian was once envisioned as a luxury resort, but its failure turned it into a breeding ground for crime. In this mission, the Black Sentinel—a private military group made up of ex-specialists and soldiers—attempts to trade a chemical weapon with Los Navegantes del Caos, a South American smuggling ring. The deal also involves a captured USIA scientist, making the situation even more dangerous.

Your task as part of LSPD’s D Platoon is to intervene before the exchange is complete. You’ll need to rescue the scientist, secure the weapon, and prevent both sides from walking away with anything.

Originally, Black Sentinel planned to betray Los Navegantes entirely, keeping both the chemical weapon and the scientist for themselves—another reason why timing is critical.

Mission Objectives

Like most Ready or Not operations, your goals are multi-layered:

1. Bring Order to Chaos – Neutralize or restrain all hostile suspects.
2. Rescue All Civilians – Secure every non-combatant inside the resort.
3. Find the Package – A cylindrical homemade bomb, always found near a restrained civilian.
4. Arrest Five Suspects – At least five enemies must be taken alive.

Additionally, weapon caches can spawn across the map—optional to secure but important to control, as suspects will rearm from them if left unchecked.

Enemies in Ready or Not Three Letter Triad

You’ll face two main enemy types here:

• Pirates – Lightly armed but unpredictable. They often rush for weapon caches to rearm, so securing those quickly can prevent them from becoming a greater threat.
• PMC Operators (Black Sentinel) – The real danger. These suspects carry rifles, wear body armor, and are much more aggressive. They will engage immediately and punish any mistakes.

Because of the heavy resistance, AP rounds and high-caliber rifles (SA58, M14, SCAR-L) are highly recommended to counter armor.

Most NPCs will shoot on sight, so making the five required arrests depends heavily on using flashbangs, Stingers, or CS gas to force compliance before they open fire.

Best Entry Points for Three Letter Triad Mission

• Avoid the Beach – It’s an open kill zone with little cover and snipers hidden in dark windows.
• Docks or Loading Bay – These are safer insertion points that provide more controlled entry paths into the resort.

Loading Bay is particularly valuable if you plan to hunt the secret room achievement, as it gives you the shortest route to the cracked wall entrance.

Loadouts for Ready or Not Three Letter Triad

There’s flexibility in gear choice, but consider these setups:

• Armor: Heavy armor with steel plates for survivability.
• Primary Weapons: Rifles with AP ammo for PMCs, shotguns with breaching capability for close quarters.
• Non-Lethal Tools: Flashbangs, CS gas, and Stinger grenades to secure suspects for arrests.
• Secondary Tools: Beanbag Shotgun or Pepperball Gun for S-rank attempts (non-lethal runs).

Any loadout technically works here, but heavy armor and consistent use of cover significantly improve survivability.

How to Secure the Package in Three Letter Triad

The package (a bomb) is always near a restrained civilian, guarded by multiple suspects. Unlike bombs in Relapse or The Elephant, it will not detonate—you only need to tag it. It emits a faint beeping sound when close, making it easier to track.

Approach carefully:

• Use flashbangs or CS gas before entry.
• Clear hostiles quickly, then restrain the civilian and secure the device.

Weapon Cache Locations in Ready or Not Three Letter Triad

A yellow cache filled with weapons spawns randomly across the map. Lightly armed suspects will attempt to rearm from it once the raid starts, so it’s wise to secure this cache early. Doing so prevents pirates from becoming more dangerous mid-mission.

Secret Room & Achievement

A hidden area adds extra replay value:

• Near the Loading Bay, head past the blue door into narrow corridors.
• Look for cracked walls with red spray paint.
• Breach with C2 explosives to uncover the Justice Uncovers Depths: Ghosts in Elysium achievement.

This hidden area also ties into the MLO easter eggs, with statues wearing Mariposa Lily headgear and graffiti connected to the faction’s lore.

Three Letter Triad Hard Mode and True Solo Strategy

On Hard difficulty, the AI here is described as the most aggressive in the game. They are often at maximum stress, meaning:

• Gun up = no hesitation. They will fire immediately.
• Gun down = hesitation possible, giving you a slim chance to command compliance.

Despite their aggression, tactical play is still viable—experienced players have achieved S-rank clears on Hard Mode even in “True Solo” runs without armor or the M32 launcher.

Three Letter Triad Tips and Strategies in Ready or Not

• Use cover constantly; long sightlines can be lethal.
• Grenades before entry—never push blind into dark rooms.
• Secure weapon caches early to prevent suspects from upgrading their firepower.
• Split your team when possible to breach rooms from multiple entrances.
• Consider the point shooting stance (Toggle Canted Sight button) for tighter spaces—it improves visibility and target ID.
• CS gas excels at locking down large interior rooms, while high-caliber rifles like the SA58 and M14 will shred PMC armor.

How to Get S-Rank in Ready or Not Three Letter Triad

To earn an S-rank in Three Letter Triad:

• Complete every objective.
• Arrest suspects instead of killing where possible.
• Avoid civilian casualties.
• Take no penalties or failed tasks.

Gas-heavy kits work well, but against PMCs consider the Beanbag Shotgun over Pepperball. Beanbags incapacitate instantly on arm/hand shots, while Pepperball’s CS gas payload takes time to disable.
