*SPOILERS GALORE!* You have been warned

.

The dudes at Eidos Montreal must have played a lot of MGS4. Like a LOT of MGS4. After finishing Human Revolution, I was shocked and pleased at how close it comes to Kojima's darling. Lets take a look at some of the similarities between the two.

• Stealth action gameplay with lots of optional shooting
• Crazy conspiracies about giant computers that control people
• Genetically-engineered protagonists
• Box robots vs Cow robots
• The Illuminati vs The Philosophers
• One-on-one boss battles with cybernetic mercenaries
• Cigarettes
• Crazy robot appendages vs crazy octo-camo suits
• Weapon upgrade systems
• Computer whiz sidekicks (Otacon vs Pritchard)

Granted, there's till plenty of differences. MGS4 is chock-full of crazy Japanese craziness (final boss fight anyone?), where Deus Ex has more western sensibilities. However both are truly excellent and I hope they inspire even more games in that genre.

Edit: Let's not forget that one of the achievements references Foxhound.
