The DLC is good if you don't expect to fly the spaceship.
It addresses the "Dark Forest" answer of the Fermi Paradox about a HOSTILE alien race.
It's an enigma in a rotating space station where you are expected to cheat to learn the truth.

I can spoil it all for you if you don't ever intend to play
Stranger alien detected the Eye before the Nomai and travelled there the SLOW way, no warp drive
On arrival they didn't like what the Eye was, the proof that everything will eventually end
They burned everything
Didn't help they demolished their native planet to build the ship which is nowhere as good
So they installed a jammer to block the eye signal, then went on to live in a simulation of their homeworld
One of them deactivated the jammer for a while, the other imprisoned him in the simulation
Some raged so much they then made it impossible to ever free him the normal way
Eventually their bodies died, they only live in their simulation
You arrive, you discover the empty station, then the simulation, you puzzle together all the above, then find a way to reach the prisoner, which involve dying and embracing the darkness
Finishing the DLC then going for the Eye you get a new person around the firecamp.
