Half-Life, but you play as a scientist NPC instead of Gordon, also Black Mesa deals with SCP entities
Gameplay is very much like Subnautica with guns, very heavy on basebuilding, crafting and exploration on a handcrafted semi-open world, you will need to achieve different goals and items to access next areas
Item finding isn't too grindy except for fishing, and resources respawn in places known as Anteverses, dimensions where our scientists go explore like Black Mesa did with Xen
