Well, they’re gory.
Well, they’re gory. Half life 1/ black Mesa (a remake with better graphics) a particularly gory, they allow you to blow up enemies and send organs and other body parts in every direction. It also has pretty disgusting looking zombies. Half life 2 is much less gory, just having more grim zombies. There’s also a new VR one called half life: Alyx which I haven’t played yet. Overall, it really depends wether or not you can handle it, but I’d say 12+
