It sounds like the Deus Ex franchise is taking an augmented knee for the foreseeable future. A report from Eurogamer says that the underperforming sales of Deus Ex: Mankind Divided combined with Eidos Montreal's focus on other projects means the follow-up title has been shelves for a bit.
Eidos Montreal has big plans for Deus Ex: Mankind Divided, as the start of the Deus Ex: Universe. In fact, Deus Ex remains at the forefront of Eidos Montreal's main page.
"Deus Ex: Human Revolution was a critical and commercial success, and from this game an amazing franchise has been revived. We are fully committed to Deus Ex here at Eidos-Montreal, we've already learnt so much and we have many new ideas for the future that we are actively working to develop," wrote Eidos Montreal's David Anfossi in late 2013, when he addressed the community as as the new head of the studio.
"We have some new projects that are now in development, and I hope you are as excited as we are for what the future has in store," says Anfossi on the current Eidos Montreal website.
Those new projects include work on the next Tomb Raider game, rumored to be Shadow of the Tomb Raider. The title leaked on Reddit after a poster noticed someone in Montreal working on a PowerPoint presentation on the subway and Kotaku later backed up that report. After that's done, Eidos Montreal will be working on the Marvel multi-game project recently announced by Square Enix. The studio is helping Crystal Dynamics on the first game in the project. Eurogamer reports that the second title developed primarily by Eidos Montreal will be based on The Guardians of the Galaxy.
"While we are still working on expanding the Deus Ex Universe, along with creating new content and updates for Deus Ex: Mankind Divided, we're also devoting our talents towards working with Crystal Dynamics and Marvel on The Avengers project," Eidos Montreal said in a statement to Eurogamer.
Essentially, more Tomb Raider and Marvel games are more important that Deus Ex. Something had to give and that franchise was it. Shame, because Mankind Divided ended on somewhat of a cliffhanger.
