Being augmented Jenson has a lot of abilities you can unlock using praxis kits that are gained either through experience points from actions or can be bought or found in the world. It's a first person shooter/role playing game hybrid though how you really want to play is up to you. I would have liked more like that throughout the game. Fortunately to compliment the main story there are a number of side quests to both find and complete which are generally speaking of a much higher quality than the main story allowing Jenson to interact with more characters and just feel more fleshed out.
Just as it was all starting to get interesting the game also ends, it's not quite a cliff hanger but it practically went 'to be continued'. I enjoyed the story quite a bit, it has some interesting themes but isn't quite focused enough on it's direction or characters and is probably the weakest aspect of the game. To sum up though you play a character called Adam Jenson a former head of security for Sarif industries, who now works for Interpol stopping terrorist attacks. Though there is a catch up video you can watch, I'd recommend playing Human revolution if you can just because it's fantastic.
This is a sequel to Deus Ex: Human Revolution.
