For the entirety of Ghost of Tsushima's first act, the player will spend their time preparing to storm Castle Kaneda and rescue Lord Shimura. After recruiting Lady Masako, Sensei Ishikawa, and the Straw Hat Ronin to his cause, Jin's last task was acquiring a tool that would allow him to scale the castle walls. In Act 1's penultimate mission, "The Iron Hook," Taka the blacksmith provides Jin with an item that does exactly that: the grappling hook. With one of Ghost of Tsushima's most useful tools in his hands and the support of his rag-tag band of warriors, Jin is finally ready to free his uncle.
