In a press release today;

"Warner Bros. Interactive Entertainment and Monolith Productions today announce a new Guardian addition to Guardians of Middle-earth with Barrow-wight Lord, who will be available for download on Xbox LIVE Arcade and PlayStation Network.

Twisted by corruption even in death, the Barrow-wight Lord is a powerful remnant of a stalwart line of Men, banished to the Barrow-downs. While living, his power was great, but in death he bears greater power with little resemblance to his original human form.

Barrow-wight Lord joins the epic character roster in Guardians of Middle-earth, with Season Pass holders having free access to him as the last Guardian as part of the pass; additional purchasable content is set to be released as well."
