Since the release of Deus Ex: Human Revolution, you'd almost be forgiven for uninstalling the original Deus Ex . After all, it's been 13 years, surely you've wrung every single drop of entertainment from its old Unreal Engine. Wrong! With the "alternate continuity" mod Deus Ex: Nihilum , there's another 10 hours of cyberpunk adventuring to be had. The Lesson? Never uninstall Deus Ex.

Here's the set-up:

"In 2049, unsavory conditions are rampant throughout the world. As soon as it becomes clear that a terrorist attack in Shenzhen, China, was carried out by perpetrators with ties to international groups and that Hong Kong may be their next target - the United Nations Anti-Terrorist Coalition (UNATCO) dispatches their first nano-augmented agent, Mad Ingram, into the city to prevent the situation from escalating any further."

The upshot of this is a new campaign, lasting around 7-13 hours. Creator 'FastGamerr' notes that Nihilum isn't designed to revolutionise its base game. "In many regards I've also tried to make it feel like an expansion pack to the original game, i.e. trying to follow the original's spirit in elements like story, gameplay and dialogue. The plot can be interpreted as a shadow parallel to the original game's story - following similar events through a different lens."

Which means it's not as wildly divergent as something like The Nameless Mod . Still, it's a handy new excuse to experience the dark and oppressive world of the first Deus Ex. As if anybody needed one.
