Warner's announced an exclusive Lord of the Rings: War in the North demo is now available to play on cloud gaming service OnLive.
For the next three weeks UK gamers will have an exclusive opportunity to try out the game with all features enabled, including multiplayer co-op.
"We all wanted to go to Middle-earth when we read The Lord of the Rings novels and watched the movies. It's a magical place," said Steve Perlman, OnLive Founder and CEO.
"We're thrilled OnLive is the first to share that magic with UK gamers with this superbly crafted title, and delighted that UK players can instantly enjoy this title through OnLive on their platform of choice, be it HDTV, PC or Mac."
The full War in the North will be available to purchase via OnLive, PC, Xbox 360 or PS3 on November 25.
