Bloodborne
From Software started off their string of dark and difficult action RPGs on the PlayStation 3 with Demon Souls, which was exclusive to the Sony platform. The two Dark Souls games moved to being on each major platform and were very well-praised.
In early 2015, From Software went a slight different route with the release of Bloodborne exclusively on PlayStation 4. The game is set in a Victorian-era city called Yharnam, and includes a slightly different approach to the combat. While the enemies will still challenge you and fit the fictional world From Software has created, you will have access to a firearm in your left arm and a melee weapon in your right. You will have to be slightly more aggressive with your attacks, but like previous From Software games, too much recklessness will get you slaughtered.
Bloodborne is currently the third highest rated exclusive on Metacritic with a rating of 92. Bloodborne is the perfect choice for people who are looking for a big challenge.
