On this page of the Returnal game guide, you will find a description of the third biome of the planet Atropos - Derelict Citadel.
The Derelict Citadel is the third biome of Atropos in Returnal. The Citadel is a very gloomy place where you will have to use the Icarian Grapnel very ofen to move between the next areas of this location.
In the Derelict Citadel, you will meet new types of enemies - Automatons, and various robots, which at first may cause you a little trouble, but over time you will learn their attacks and intuitively will avoid them.
The final stage of the journey through the Derelict Citadel is rooms and narrow corridors filled with laser traps. Before you try to go through the lasers, take a moment to familiarize yourself with the movements of the individual beams. Keep in mind that performing a dash at the right time will protect Selene from getting injured.
In some situations, Selene may lose the ability to perform a dash - in that case, you will need to be especially careful.
The most dangerous opponents
The first dangerous and difficult opponent is the kamikaze robot. Although it does not have any additional attacks, it charges at Selene and self-destructs, causing much damage.
It is best to finish this opponent before it approaches you. You can also try to dodge it, but be careful not to get too close to the enemy (stay out of the red area) because you will cause an explosion.
In the Derelict Citadel, you will also encounter levitating glowing spheres resistant to damage and have several different skills. The spheres can fire many projectiles in all directions, summon laser beams, and teleport to random places.
The last and most dangerous opponent, who inhabits the Derelict Citadel, is a large robot Automaton. The enemy is resistant to damage, but shooting at a weak point (head) will damage it more, and knock him out faster, which will make the fight easier.
Automatons have many offensive skills and can also launch their hand, catch Selene and pull her to them - you can protect yourself from this move by doing a dash right before being caught.
At the end of the Derelict Citadel, you will have to face the third boss in Returnal, Nemesis. A detailed description of the Phrike boss fight, as well as tips and tricks on how to defeat it, can be found on the Nemesis - boss, how to defeat? page.
