On this page of the Returnal game guide, you will find a walkthrough of the sixth biome on the planet Atropos - the Abyssal Scar.
The Abyssal Scar is the sixth and final biome on the planet Atropos in the game Returnal. The Abyssal Scar is a unique underwater environment where gravity works slightly differently, enabling Selene to jump much further.
While exploring the Abyssal Scar, you don't have to worry about running out of oxygen, and all weapons work exactly like they did on the surface. Due to the reduced gravity, it can be a bit difficult you to jump between crevices, but you'll definitely get used to it over time.
As you explore this biome, you'll find an extremely useful gadget, the Delphic Visor, which will allow Selene to see previously imperceptible objects - glowing spheres that can be shot at to discover passages leading to previously inaccessible areas of the map.
The most dangerous opponents
In this biome you will also encounter levitating spheres, which you certainly had the opportunity to fight while exploring the third and fifth biome on the planet Atropos. These orbs can now fire vertical and horizontal laser beams, making the fights against them a little more difficult.
A very difficult opponent is the distorted creature which you will have to face about halfway to the final boss of the game Returnal. During this fight you won't have much room to maneuver and the enemy will be constantly using their skills.
At the end of the Abyssal Scar biome, you will have to face the fifth and final boss of the game Returnal, Ophion. For a more detailed description of this boss fight, as well as tips on how to defeat the boss, check out the Ophion - boss, how to defeat? page.
