The Hidden Secrets Pack offers three extra missions that were originally available as pre-order bonuses, including the the Lost Mayan Ruins, the Ghost of War and a Dangerous Secret. Hidden Secrets also offers two single-player costumes (the Captain of the Aquila uniform and Colonial Assassin outfit) as well as two multiplayer characters (the Redcoat and Sharpshooter).
The Battle Hardened Pack adds three new multiplayer maps -- Charlestown, Fort St-Mathieu and Saint Pierre -- as well as three new multiplayer characters: the Governor, Highlander and Coyote Man.
The Hidden Secrets Pack originally came to Xbox 360, PlayStation 3 and PC in December, while the Battle Hardened Pack was released last week. Assassin’s Creed III’s Tyranny of King Washington downloadable content is still set to arrive later this year.
