Just finished playing this videogame and I've to say: game of the year candidate.
The story is based on a Celtic myth. You play as Senua, as she embarks on a very personal journey through a hellish underworld.
I'm always relutant in buying indie games. I was afraid this was another "walking simulator" like Outlast or Journey, but I was wrong. I'm glad I decided to play, because it was a fantastic experience.
Just a tip for those who will play: do it with a good headphone, the immersion is fantastic, you feel like you're really in Senua's mind.
The game is available for PS4 and PC. I played on PS4, but for those with good gaming PCs it may worth it more, since it's cheaper on Steam as usual.
