Sleeper agents are spies placed in a foreign country with no memory of their past identities. They are given new identities, jobs, and false memories to blend in as normal citizens. In fiction, sleeper agents are sometimes unaware of their true identities and are hypnotized or brainwashed until they are activated by a series of code words. In reality, sleeper agents have been used for spying, espionage, sedition, treason, and assassinations. To wake the sleeper agent, one must deliver the code words that will trigger the agent's memory and activate their mission.

What You'll Learn

Find the stained white T-shirt
To find a stained white T-shirt, you must first identify the type of stain. This will help determine the best course of action for stain removal. Common sources of stains include food and drinks such as coffee, tomato sauce, and red wine. Other stains may be from ink, grease, or blood.
Once you have identified the type of stain, you can proceed with the appropriate treatment. Here are some general guidelines:
- For coffee stains, you can use bleach, dish soap, hydrogen peroxide, lemon juice, or a combination of vinegar and baking soda.
- For red wine stains, it is recommended to rinse the affected area with cold water, blot with a paper towel, and then apply a paste of baking soda, dishwashing liquid, and hydrogen peroxide.
- For tougher stains, oxygen bleach can be used, either applied directly or during a regular wash cycle.
- For blood stains, hydrogen peroxide can be effective if the stain is fresh.
- For sweat stains, lemon juice is recommended, mixed with equal parts water, and rubbed into the affected area.
- For ink and grease stains, a natural remedy is to use a salt and cold water solution, letting it soak for 20 minutes before washing the garment with cold water.
- For older, yellowish stains, a mixture of peroxide and dawn power wash, followed by sun exposure, can be effective.
After treating the stain, it is important to wash the T-shirt according to the care instructions on the label. Use cold water and avoid putting the shirt in the dryer, as this can set the stain. Instead, let the shirt air dry in direct sunlight, which can also help brighten the fabric.
By following these steps, you can effectively find and treat stains on a white T-shirt, restoring it to its original condition.

Locate the glowing green console
To locate the glowing green console, players must first obtain a stained white T-shirt, which can be found in crates scattered around the map in the Call of Duty battle royale game mode. Once you have the T-shirt, make your way to the Array location on the Blackout BO4 map. Head to the building in the middle of the Array and find the glowing green console. Interact with the console using the square or X button.
The Array is a central location in the Blackout map, and it is where players must go to activate the Sleeper Agent. The building in the middle of the Array is the main structure in this location, and it is where the glowing green console is located. This console is essential to activating the Sleeper Agent and unlocking Mason as a playable character in Call of Duty: Black Ops 4.
It is important to note that the process of waking the Sleeper Agent and unlocking Mason can be quite challenging and vague. Players must complete all the necessary objectives in a single match, adding to the difficulty. Additionally, the Sleeper Agent has specific mechanics that make it a unique and intriguing feature in the game. When activated, the player will be disguised as an operator for the opposing team, either Rogue Black Ops or Crimson One, complete with a dark vignette around their HUD.
There are three states that the Sleeper Agent can be in: Hidden, Tracked, and Revealed. In the Hidden state, the agent appears as a friendly operator to enemy players with a blue nameplate. If the agent is shot or comes into the line of sight of an enemy with Vigilance, they enter the Tracked state, still appearing friendly. The Revealed state occurs when the agent fires an un-silenced weapon, causing their nameplate to turn red and their disguise to be deactivated.

Activate the button
Activating a sleeper agent is no easy task. It requires a significant amount of planning, preparation, and, most importantly, patience. Here are the steps to press the metaphorical "button" and activate a sleeper agent effectively:
Step 1: Recruitment and Placement
The first step is to identify and recruit individuals who are suitable for the role of a sleeper agent. This process can be challenging, as the ideal candidates will possess a unique combination of skills, including the ability to assimilate into the target environment seamlessly. They should be able to cultivate relationships, build a career, and appear as normal citizens. Once recruited, these agents are placed in key positions within the target country or organization, where they remain dormant until activation.
Step 2: Building a Cover
During their dormant period, sleeper agents focus on establishing a solid cover. This involves leading a normal life, blending in with the surroundings, and refraining from any suspicious activities. They build careers, often in strategic areas like defense or diplomacy, and cultivate relationships that could prove advantageous in the future. This phase can last for years or even decades, during which the agents do not engage in any spy-related activities.
Step 3: Activation Signal
After the sleeper agent has been successfully integrated into their new life, the activating organization will send a signal to initiate the mission. This signal can vary depending on the specific operation and the agent's conditioning. It could be a secret password or passphrase, a postcard with a significant picture, or even a specific activation phrase that triggers the agent's response. This step is crucial, as it transforms the seemingly ordinary individual into a spy, terrorist, or operative ready to carry out their assigned tasks.
Step 4: Mission Execution
Once activated, the sleeper agent springs into action, carrying out the instructions provided by the activating organization. They leverage their positions, relationships, and access to confidential information to execute their mission. This can involve espionage, sabotage, intelligence gathering, or any other tasks required by their handlers. It is important to note that counter-intelligence agencies may become aware of the sleeper agent's activities during this phase.
Step 5: Contingency Planning
Activating a sleeper agent is a high-stakes maneuver, and contingency planning is essential. The activating organization should have protocols in place in case the agent is compromised, captured, or fails to respond to the activation signal. These plans might include alternative means of communication, escape routes, or backup agents who can step in if needed.
Pressing the "button" to activate a sleeper agent is a complex and delicate process. It involves a careful balance of strategic planning, covert operations, and effective handling of the agent. When done successfully, it can provide a powerful advantage to the activating organization, but it also carries inherent risks and uncertainties.
