From now until Sunday, you can snag the definitive version of Deus Ex: Human Revolution for only $5. This version of the game fixes some AI issues, revamps the boss battles to be more fun and far less frustrating, and adds in some extra missions for a bigger storyline. As someone who enjoyed the original release a few years ago, this gussied-up version seems even better. The original game was definitely hampered by the boss battles, and once it came out that those were farmed out, it made a lot more sense. At only $5, this is a no-brainer if you even remotely enjoyed the original release. Heck, if you’ve just heard about how great it is, get this to see why it got so much praise.
