Deus Ex Human Revolution is a game that you will lose sleep over because you want to just play it all day.
You don't need to have played the first two games to enjoy Human Revolution but I recommend you play the first game because if you do you will notice how a bunch of things fall into place in Human Revolution. In Deus Ex Human Revolution you play Adam Jensen a man who is fresh out of the package because he had major mechanical augmentation surgery done to his body without a choice. Deus Ex Human Revolution is a story only game and its story is a great one. It took me 30 hours to complete my first play trough and I looked for a lot of hidden things so I spent more time. Also more replay value is added here because if you do certain things in Deus Ex the plot can take a few twists depending what you do. The choices you can make or simply not good or bad and the choices are made at your will so no button press choices will every come your way. The story takes a few hours to get into but once you get over that hump you get a story that you will lose sleep over because of the questions that it asks. The topics in Deus Ex cannot be answered with simple one liners but more so with complex theories. Augmentation now isn't a big ethical debt today because people who get artificial limbs in 2011 don't get them because they want to be stronger, better or faster they get them because they want mobility back. Overall Deus Ex has a very strong story that takes time to get into but once you do you won't ever forget the tale, and it has a bunch of fan service to people who love or played the original games.
The gun game in Deus Ex is great. Shooting a high powered gun has just the right amount of punch in it to seem realistic. If you are more on the non lethal side of the fence then your experience is a tad limited because there are only two non lethal guns and you will get boarded of the same two guns. Almost every gun you come across besides the stun gun can be upgraded with upgrade packs that you can either buy or find throughout the world. The upgrades to each gun are unique so every gun can become their own deadly killer. The overall combat in Deus Ex feels great but I found that I became more wrapped up in the game when I was going for a stealth agent approach. By going stealth I was able to get more depth out of the story.
Deus Ex Human Revolution is certainly not a game without bugs. A few times when playing Deus Ex you will find you self seeing the AI do weird things. For instance when you go into do a contextualized take down some times the guy you are taking down will be miss placed so it looks like your taking down the air. Also when you doing Take downs the AI around you freezes up, this feels really unnatural and is really weird to see a bunch of people still when you are killing there buddy. The AI sometimes will not find real cover so they might be standing around doing nothing when you clearly have a gun in their face. On top of a few graphical bugs Deus Ex can freeze up your consul. The freezes happened to me the most when I was using a really powerful shot gun. A plus however is that the load times are not that bad.
The graphics in Deus Ex are good in my opinion because the square like cyber punk figures is what the artists wanted. The character models really merge with the overall mood of the game. The only problem I have with the graphics is that sometimes when you pop out of cover to use you gun the frame rate might dip and textures might seem a bit distorted. This problem really doesn't effect the game play experience at all and the new cyber punk feel is nice to see in the age of war torn city art directions.
Deus Ex Human Revolution is an augmented experience that you will remember for years to come. The story will wrap you in a web that will make you never want to put the controller down and the freedom of choice outside of boss battles can make for very interesting game play scenarios. I give Deus Ex Human Revolution a 9 out of 10 because of its strong narrative, open level environments, good gun play, great story manipulation, great art direction, and innovative RPG elements. The two things that could have made Human Revolution a 10 out of 10 are the choice to let a boss live and less graphical glitches. If you want a game that can last a life time that offers many ways of play and that has an epic story then I recommend Deus Ex Human Revolution, and if you are on the fence about the game … just get it already, you will regret it if you don't.
