How to Complete Two Factor Authentication Mission in Modern Warfare 3 Zombies

Welcome to our friendly guide on how to successfully complete the Two Factor Authentication mission in Modern Warfare 3 Zombies. This mission requires you to defend a ground station while completing various objectives. Follow these steps and tips to ensure your success!

In order to start the Two Factor Authentication mission, you first need to locate and activate the seismic refractors. These refractors are vital in creating a secure connection to the ground station. To find them, use the Tac-Map provided in the game. Look for blue squares on the map that have skull icons. These indicate the locations of the refractors.

Once you've identified the locations, head towards each one and activate them. There are three refractors in total that need to be activated. When approaching a refractor, interact with it to initiate the activation process. Be prepared for zombies and mercenaries to attack while you're activating the refractors, so keep your team on high alert and ready to defend.

After activating the three refractors, you will need to activate a nearby server to begin the upload process. Locate the server and interact with it to initiate the upload. This will move you to the next objective.

As you progress through the Two Factor Authentication mission, you will encounter a dust storm gathering near your location. This indicates the arrival of mercenaries who will try to disrupt your mission. Your task is to eliminate them and defend the ground station.

Keep an eye out for the mercenaries as they approach. They can come from multiple directions, so stay vigilant and communicate with your team to cover all angles. Use your weapons and abilities effectively to shoot and eliminate the oncoming mercenaries. Aim to achieve a total of 20 kills during this contract to successfully complete this objective.

One of the key objectives in the Two Factor Authentication mission is to protect the server. The server contains crucial data and must be defended at all costs. To do this, you need to maintain the computer's health above 60%.

During the defense phase, keep an eye on the blue bar with a percentage on the left side of the screen. This bar represents the timer for the defense. Make sure the percentage stays above 60% to ensure the server's health is not compromised. If the percentage drops below 60%, prioritize defending the server to prevent further damage.

Working as a team is crucial during this objective. Assign someone to manage the station while the rest of the team focuses on dispelling zombies and mercenaries. Communication and coordination are key to successfully completing this objective.

Once you have successfully defended the server and maintained its health above 60%, the upload process will be completed. Congratulations! You're one step closer to completing the Two Factor Authentication mission.

As a reward for completing the mission, you will receive the Death Perception recipe. This powerful ability allows you to see hidden enemies and traps, giving you an advantage in future matches. To craft the Death Perception, follow the crafting instructions provided in-game. Make sure to gather the necessary ingredients and allocate enough time for crafting before the next match.
