If you’re anything like me, your Xbox dashboard is probably a rotating door of massive open-world RPGs and competitive shooters. But every now and then, a game comes along that just completely hooks you with its vibe alone. Enter Luna Abyss, the new single-player, story-driven action-adventure from publisher Kwalee, and it is a certified trip.

I’ve been spending some quality time diving into its depths, and honestly? It’s exactly the kind of atmospheric, frantic sci-fi horror I didn’t know I was craving. Here is my breakdown of why this indie gem deserves a spot on your hard drive.
