GR: Blood does many different things in The Last of Us. It streams down Joel's face when an enemy tears the flesh from his neck. It gushes out of any number of important arteries from a decapitated foe. It pools around the humans perforated with a shotgun and glistens with the light's reflection. In one scene, fellow survivor Bill lops the head off a zombie, and as Joel pushes the newly headless corpse off, blood soaks its shirt collar and spreads as it would in real life. Unlike the liquid freedom of blood, though, your options in a world mangled and destroyed by the Cordyceps fungus—a real fungus that behaves as it does in the game, even if it can't turn people into bloodthirsty monsters in real life—remain limited.
Here are the options: stay in a highly militarized quarantine zone and deal with the oppressive military organization that continues to guarantee your safety, join up with any number of different gangs looking out for themselves, or join the Fireflies, a group of freedom fighters looking to ensure mankind's survival, despite the state of the world. If that sounds like typical zombie schlock, be thankful that Naughty Dog have instead focused on building one of the most human games you'll ever play, both emotionally exciting and physically exhausting.
