Where to expect the third alien queen?

1. The third Alien Queen is encountered during Mission 5 - Nuclear Protocol. This happens during the second visit to Pioneer Station.
2. One of the main tasks of the mission is reaching Cerberus Room with the intent of disabling Cerberus Protocol.

When you try to use the terminal to open the door, you'll receive a warning about an upcoming battle.

Preparations

1. You'll learn of the Alien Queen right after entering the Cerberus Room, and this time you cannot prepare.
2. You may not know who the enemy inside will be, but you can prepare some even before opening the door. Replenish ammunition supplies, heal your marines and optionally create a shelter in one of the neighboring rooms to lower stress levels of soldiers.

How to defeat the queen in the Cerberus Room?

Start the battle by taking care of a group of facehuggers attempting to get in melee range of the marines. Use skills such as grenade launcher, flamethrower and other offensive abilities to eliminate them quickly.

1. Do not try to set up mines or Sentry Guns are there is no time for that. Start running around the Cerberus Room to stay at a distance from the queen. While making circles, you'll encounter some synthetic enemies. There aren't that big of a threat, as they are slow.
2. Look for opportunities to detonate explosive barrels by hitting them with weapons. They inflict heavy damage on the queen if she is caught in their range and set extended areas on fire.

1. Only after you are at some distance from the boss, use Suppressive Fire to slow the queen down.
2. To deal damage to the queen, use offensive skills such as U1 Grenade Launcher or RPG Launcher. If the queen starts to charge, quickly run to the side so that the marines do not get hit and knocked to the ground.

1. Focus on depriving the queen of her entire red health bar. Only after killing the queen start attacking synthetic enemies. U1 Grenade Launcher can come in handy here. Synthetics are slow, which means you don't have to compensate much when aiming.
2. After the battle, approach the queen's corpse to collect xenosamples and acquire a new Xenotech project.
