A very clever a dark futuristic journey.
Deus Ex is basically fantastic value for money as the main game lasts a good 15 hours at least and can take a lot longer if you do more of the side quests and read more of the many emails and ebooks found around the world. The game has multiple routes to try to achieve any objective and although they almost always boil down to a door you can hack to get a short cut to the target, a long well guarded route or a selection of vents to crawl through they all add a good twist to the game play. i recommend using a mixture of all the tactics to get the most of the game.
The graphics although not great compare well with other games such as borderlands or fallout and have a cool cyber punk style which makes up for the technical failings.
If you are looking a deep tactical shooter with an interesting story and setting look no further. Its a blast to play and is still expanding with DLC coming out over the next few months.
