Where is the Queen's lair in the Trimonite Mine?

1. The Alien Queen in Mission 11 is the last one of the campaign. If you have killed all the previous queens, defeating this one will be rewarded with a gold trophy - Regicide.
2. You can reach the Queen's nest while exploring the Trimonite Mine in the Olduvai Dig Site, which is under the control of the Darwin Era cultists.

1. The boss's lair is on the main level of the mine, in the nest of the swarm. You will reach it searching for Cassandra.
2. Defeating this Queen is mandatory to access the subsequent passage and continue the mission.

How to kill the Xenomorph Queen in mission 11?

1. Don't rush to the lair and prepare for the fight before the Xenomorphs detect your squad.
2. You can set up, for example, near the western entrance to the lair. Primarily, take care of the placing the Sentry Guns and turn them towards the Queen.
3. Additionally, a good idea is to set up mines - at least one should be placed at the southern alien nest. It might explode if a creature comes out of the nest.

1. Begin the battle with the Queen by performing a strong attack and provoking the monster to head toward the squad. Don't fight in the lair, because there are Facehugger Eggs there. It's best to retreat to the Sentry Guns and let them shoot Facehuggers.
2. After the Queen starts moving, activate Suppressive Fire for at least one soldier to slow her down. You can also weaken the Queen faster using, for example, a rocket launcher, a grenade launcher, or the Precision Shot ability.
3. After the battle, get rid of the remaining Xenomorphs. The Queen will leave behind 8 Xenosamples, but unfortunately, you will not find any new Blueprints.
