RPG Codex Review: Deus Ex: Mankind Divided

Mankind Divided is the 'sequel to the prequel', following Adam Jensen after the climax of Human Revolution. Human Revolution was a clever, well-constructed, and worthy sequel to the original Deus Ex - if not quite surpassing it. Is Mankind Divided a further step in the right direction?

Note: as I want to discuss and critique the game, this review will contain some mild spoilers for Mankind Divided (of a similar degree to what you'd get watching some of the trailers and teaser videos released by the developer), and more serious spoilers of Human Revolution and Deus Ex itself. One can scroll to the final heading to see a (wholly spoiler-free) summing up and recommendation whether or not one should buy the game.

Conclusion: Not enough steps forward, a few steps back

Mankind Divided is so near and yet so far. Its elements mostly build upon the strong foundations of Human Revolution, but occasionally they retreat back from earlier triumphs, and leave some major flaws uncorrected. It is cleverly written but with a few too many mis-steps, and a central lacuna around the player character himself. At its best, the strengths of the game combine harmoniously to produce one of the best opening thirds in computer gaming; the fatal weakness is that it is no more than an opening third, and the game ends on a deeply imperfect cadence with too many themes undeveloped, leave alone resolved.

The game indicates considerable talent, and the writing team know their craft well. My hope is that the impressive story Mankind Divided intimates has been mostly written, and that subsequent additions to the franchise will adroitly fulfill the undoubted promise manifest here. Yet these games do not yet exist, and thus Mankind Divided remains a promissory note for a series of games which in combination may form a masterpiece. Unless and until that happens, this opening act, despite its qualities, cannot justify its own purchase.
