I really enjoyed the combat and the unique story...until the ending. The game has interesting combat mechanics, but literally pushes you into irrelevant decisions and then makes you out to be the bad guy, even when it is clear that Booker doesn't want to be. The DLC is even worse. Great chance to conect the Infinite story with the first 2 games, but then it is ruined by really awful story that destroys the characters. Soooo much awesome possibillity messed up by intentionally idiotic and pushy story arcs.
Even for a game that is almost 10 years old, this one is still quite the challenge on Normal, especially at the beginning when resources are low and hard to find. Teh story kind of dumps in you in it with no hand-holding, and the controls are a little klugy compared to other FPS titles, but it is still fun.
