Aliens: Fireteam Elite is a co-op action game that is split into four campaigns. The first campaign, Priority One, starts with Ingress, a rescue mission in which you must locate Dr. Hoenikker aboard the Katanga.
This mission introduces you to many of the basic mechanics in Aliens: Fireteam Elite. If you're finding all of that a bit overwhelming, this guide will take you through Ingress step by step, so that you can come to grips with everything that Aliens: Fireteam Elite has to offer.
Priority One: Ingress Walkthrough
When the mission begins, head out of the starting room and turn left. Follow the corridor down and continue towards the objective marker. When you find the terminal, interact with it to download the refinery plans.
After doing this, you need to head to Hoenikker's PDT. On the way, you will hear and see lots of movement, but you won't come across any enemies until you arrive at the objective, so you can continue safely for now.
How To Find The Intel In Priority One: Ingress
As you move further through the Katanga, your team will mention that there is acid damage upon entering a room with a large central pillar.
Turn left and head through the open door to spot a red explosive barrel. The objective will direct you to the right, but first head left and move to the end of the corridor. You'll find some Intel that will unlock new dialogue options back at base.
Continue towards the objective and get ready for your first Xenomorph encounter. When you find Hoenikker's PDT, Xenomorphs will break through the ceiling vents and attack from both sides.
To kill them quickly, shoot the explosive barrels scattered around to cause huge explosions. After killing them, continue down the corridor and interact with the locked door on the left.
This door is clamped shut, so you need to saw through it. Whilst you do that, Xenomorphs will attack again, so make sure your teammates are prepared to defend.
When it opens, move through the corridor and kill the Xenos waiting to ambush you on the left.
In the next room, use the ammo box to refill your ammo. After, a horde of Xenomorphs will attack from either side of the room. Here, you will find Xenomorph Bursters and Xenomorph Spitters, two special Xeno variants.
Bursters die in an acidic explosion, whilst Spitters fire acid at you. Both have more health than regular Xenomorphs, so stick with your teammates and work together to kill them.
How To Find The Hidden Crate In Priority One: Ingress
When the onslaught ends, interact with the terminal to unlock the exits. This will give you a new objective, but search the room before you leave.
You will find a crate in here that contains some powerups that you can use later in the mission. This crate can spawn in various positions in the room, so look all over.
After, head into the next room and interact with the terminal to download the Refinery Ops logs. This will trigger a Xenomorph attack which will introduce you to the Xenomorph Drone.
This is a bigger Xeno that will dart through the room and deal much more damage than regular enemies. Use the powerups you found in the crate to kill it faster.
When the transfer is complete, follow the objective marker through the previous room and into a new corridor.
As you turn the corner, look at the ceiling to spot a Xenomorph Prowler waiting to pounce on you. Dispatch it quickly before it leaps onto you and starts attacking.
After, follow the corridor and continue until you reach the next terminal. Here, you will find an ammo box, a medkit, and a crate containing a turret.
Interacting with the terminal will initiate another Xenomorph attack, so place the turret down beforehand. Then, use the terminal to start the battle.
Xenomorphs will attack from either side of the room, so have the turret on one side whilst you defend the other.
During the fight, a Xenomorph Warrior will appear. This is an armored Xeno variant that is much tougher than other types that you've encountered before, so get your teammates to focus on it.
When the fight ends, follow the objective marker into the next room, where the attack will continue. This fight is a lot harder, as you won't have any defenses or explosive barrels.
Use any skills and abilities that you have at your disposal to make quick work of the approaching enemies.
As you enter the next room, another fight will begin. This should be much easier than the last, as there are explosive barrels placed throughout the room.
Use them to deal massive damage to the Xenos and wipe them out before continuing towards the objective.
How To Survive The Final Battle In Priority One: Ingress
When you find the elevator, resupply and open both of the nearby crates. One will contain a turret, which you should place down straight away.
The other has incendiary rounds, which you can use in the upcoming fight. When you are ready, interact with the elevator to call it and start the final fight of the mission.
Swarms of Xenomorphs will charge from the other side of the room indefinitely, but you only need to survive for three minutes.
As before, use explosive barrels to your advantage, as they can wipe out large groups with ease.
Xenomorph Warriors will also spawn during this battle, so save Incendiary rounds for them. When you spot a Warrior, have your whole team fire at it so that it dies quickly. Your turrets should be able to fend off the other Xenomorphs whilst you focus on tougher variants.
When the elevator arrives, jump in to finish the battle and complete Priority One: Ingress.
