The only game where you'll want to find all the collectibles. The story is pretty good too.

Basically an orc murdering simulator and one of the most fun experiences I've had playing a video game. The Arkham inspired combat is visceral and responsive and never gets old. The stealth mechanics are lifted straight from Assassin's Creed but with additional features such as the ability to Brutalize orcs and make their companions run off in fear. The voice acting is top notch (seriously who did they get to voice Gollum he sounds exactly like Andy Serkis!) and the story remains entertaining to the end. Highly recommended and I can't wait to play Shadow of War.
