On this guide page, we described the correct path through Basement 1. You will find out, among other things, how to get to the place where you can restore power, how to unlock the garage, and how to resume the mission on the next deployment.

Basement 1 map in mission 6

After using the elevator to go down to the basement in mission 6, you will receive the task of reaching the atmospheric processor generator. You cannot head straight to the main mission objective, because you will encounter closed doors and indestructible barricades.

Here are the most important locations on the Basement 1 map:

1. Point 1 - This is the elevator where you will begin.
2. Point 2 - This is the southern corridor, where you will learn about the option of restoring power supplies.
3. Point 3 - This is the basement lighting generator room. It can also become a shelter for marines.
4. Point 4 - This is a garage, where the M577 personnel carrier is located.
5. Point 5 - This is the place where you can re-deploy and continue mission 6.
6. Point 6 - This is the eastern corridor leading north to the objective of mission 6. You will reach it after passing through the garage.

How to get to Basement 1?

1. You will reach the elevator in the second part of mission 6, after passing through the Helium Storage and Pressure Control Room and fighting a big group of xenomorphs.
2. The elevator is in the southeast corner of this part of the map. Use it to get to the Basement 1 level.
3. You will not be able to reach the atmospheric processor by going in a straight line. The main character encounters various obstacles on the way - locked doors that can't be opened or obstacles that cannot be blown up.

How to get to the basement generator?

1. You need to turn southeast. At some point, the lights in the basement will be turned off. Reactivating the generator is an optional mission objective, but it will make your life easier.
2. Watch out for single xenomorphs patrolling the area - it's best to take them down quickly with a sniper rifle to avoid alarming the area.
3. Be careful in rooms with facehugger eggs, because it's hard to destroy them while remaining unnoticed. Follow the main corridors or quickly run through the areas with eggs before facehuggers hatch.
4. Upon reaching the Generator Room, use the terminal to restore power. This is also the perfect place to create a shelter and save the game.

Exploring the garage and re-deployment

1. After leaving the Generator Room, continue heading east. Again, avoid xenomorphs and rooms with facehugger eggs.
2. Reach any of the entrances to the garage and order one of the marines to open the door (no tools are required for this).
3. There is an M577 personnel carrier in the garage and we described it in more detail on the ARC and M577 page.

1. Mission 6 will be interrupted at this moment, as the unit will return with a new carrier to the USS Otago. This will unlock a fifth squad member for the subsequent deployments.
2. You must wait until the next day to deploy and return to mission 6. Choose the basement landing spot as the place to resume the mission, the one near the garage where the APC was.

Eastern path to the atmospheric processor generator

1. You must go through the garage again where the M577 vehicle was located. Choose one of the eastern exits from the garage.
2. Head north and once again watch out for xenomorphs and facehugger eggs. The eastern corridor will lead you to the processor center.
3. The subsequent objectives have simple routes and you shouldn't get lost again. The squad must once again defend themselves against the xenomorphs and reach the elevator traveling to Basement 2 level.
