Deus Ex: The Fall is a first-person role-playing stealth-action game developed by Eidos Montreal. It is the fourth installment in the series. The game serves as a prequel to Deus Ex: Human Revolution.

The year is 2027. Human augmentations are a common thing. Bex Saxon, an ex-SAS, gets employed by a PMC called Belltower Associates. Hiding from the Illuminati in Costa Rica, Ben starts to experience augmentation rejection syndrome because of a global shortage of Neuropozyne which suppresses the symptoms. Ben unravels a global conspiracy revolving around the drug and tries to warn the World Health Organization.

Like the previous installments, the game features a high degree of role-playing. Players are able to upgrade their augmentations, unlocking more and more abilities. An inventory system is also present. Players have the option to use lethal or non-lethal approaches using different takedowns, and a wide range of weaponry. The levels are fairly open-ended so it is possible to complete a mission without even confronting the enemies.
