I went into this game completely blind, to say I had not heard a single thing about how this game played other than it was a first person shooter with some special things. I was pleasantly surprised by this and in fact, it was fun and a great story.
The main premise is you are involved in a plane crash and find yourself on the doorstep to a city that was built underwater. Through the course of the game, you come to find out your true purpose, the history of the city and just what is going on. This is my key point for liking this game. The story is well-thought out and every piece fits. Sure parts are a little funky at times but everything you are doing makes sense with what is going on around you.
Now, the gameplay is solid. You have a of tools at your disposal and you know what they are used for. Then comes the twist, using plasmids in conjunction with a weapon yields different results. It keeps the game fresh but at times you will just be running around and trying to survive. This game suffers from what I like to call, useless cover syndrome.
Useless cover syndrome is when a game gives you a cover system but then allows the enemies to quickly make it useless. Early on, you learn that you should crouch behind things to avoid getting shot at. The only issue I had was often I was being shot through the cover or what I thought was cover was in fact just a set piece. It is frustrating when you are trying to use the systems the game comes up with and they don't work.
Through and through, this game is atmospheric and even at the lowest points, it is never dull. I give this a recommendation just purely for the story. It is a very well-thought out piece of writing and it even makes you wander about things if our world had just been a little bit different from the reality we live in. Sure it is a fantasy story but it also has the pieces of plausibility that give it an extra edge.
