The Lord of the Rings: Gollum releases September 1 on PC and consoles
Gollum will be a "story-driven stealth adventure" that follows Gollum's unseen actions during the first few chapters of The Fellowship of the Ring, as he sets out on a "perilous journey that leads him from the dungeons of Barad-dûr to the realm of the Wood-elves in Mirkwood." Player choice will apparently be an important factor in the game, with a branching narrative that will have Gollum encounter many familiar characters from the book series. Gollum's other half, Sméagol, will also play a role, with players having the option to let him take over and make important decisions.
