Much to the delight of Deus Ex: Human Revolution fans, myself included, Square Enix announced downloadable story-driven content shortly after the game was released. Missing Link fills in the blanks...

+ Clears up a few questions; + Game play is consistent with original

Too much backtracking; Some graphical glitches; Story is not compelling

Adam wasn't napping for the three days he disappeared during Deus Ex: Human Revolution. The big lug starts Missing Link strapped into an interrogation chair in the bowels of a Belltower freighter, but a mysterious new ally soon frees him to cause fresh mischief.

+ Nerve-fraying stealth; heart-pounding combat; intricate new environments, + Every choice matters, from upgrades and tactics to a single troubling moral dilemma

? Are Adam's six-pack abs the result of exercise or augmentation

When a game is done with taste and style, you pretty much recognize that from the first few minutes of gameplay. Eidos Montreal invested a great deal here, particularly when it comes to art direction, visual effects and sound.

It hooks you from the beginning and keeps you hooked to the end; superb sci-fi ambience; excellent music; sound effects and voiceovers; an engaging blend of stealth; action and RPG

Players can't map their controls; AI unresponsive to sound at times; a few other issues here and there; though certainly nothing that spoiled the immersion

Evaluating Deus Ex: Human Revolution based on how similar/dissimilar it is to its acclaimed grandfather, the acclaimed and seemingly infallible Deus Ex , and/or Human Revolution 's divisive predecessor, Deus Ex: Invisible War , will be a natural inclination for anyone who has played the previous two...

Inconsistent enemy AI; Jarring disconnect between cutscenes and gameplay; Illuminati clumsily included

DXHRDC is the best version of the game, bar none. With a slew of brilliant changes and new features, it's the one to get.

A lengthy and detailed single player experience that has been long overdue this year. Worthy of your money and time.

A constantly interesting and fun experience with a stealth shooter that showcases many shades of the great Metal Gear Solid franchise.

Nagging blemishes that cut back the game's sense of freedom and scale and load times that range from annoying to debilitating on console and PC.

Sure, it didn't deliver the exact same brand of action-RPG that the legendary original game did back in 2000, but it did bring back the stealth-action gameplay with a few new twists and showed us...

Deus Ex: Human Revolution - The Missing Link is a disjointed but ultimately enjoyable return to Adam Jensen's adventure.

Level design lets you approach obstacles as you see fit; Some creepy and atmospheric story moments; Evocative art style and color palette

Too much backtracking and body scanning; Various presentation flaws; The AI is still as dumb as can be

Games often try to address philosophical issues; the good ones manage to achieve some degree of nuance or subtlety in the questions they pose while the bad ones beat players over the head with an ideological mallet.
