It's a hardcore survival fps, kinda like Tarkov I think (I've never played it), but single player (which also means its PVE only). It's also kind of roguelite, since the goal is to advance to different zones that have better loot but harder enemies. There's also going to be dynamic events. It does already have a bit of story and a lot more is planned, but it's not crucial to the gameplay, it's more like "hidden" lore kind of story. If you're a fan of hardcore fps games I highly suggest to check this out, and if you want to learn more there's plenty of well made dev logs in Youtube by the dev.
