It was good in many ways. And it expands on dead space in many ways mechanically, it just didn’t follow through in some aspects.
The guns are cool and there’s a very satisfying melee system.
But the melee system is overpowered, which means monsters are less scary. The sound-based stealth sections where you go through rooms full of blind monsters that allegedly react to sound, have the monsters being completely deaf to melee kills, which means you can just walk up to them one by one and clear the room.
And you’re right about the story. The game should have had LORE, but it’s just the bare minimum generic excuse to have a horror setting.
