s Ex Universe, the companion app for Deus Ex: Mankind Divide, gives you access to videos and images from this franchise's last two games. That said, it's nothing exclusive, just the same content you can find on any gaming news site.
You can also use Deus Ex Universe to pre-purchase a copy of Deus Ex: Mankind Divide. That said, and despite it being a good idea (any game from this franchise is excellent and promises great content), maybe it's not the smartest idea to buy it from this app and so far in advance.
Deus Ex Universe is a companion app that (like all companion apps) is a bit green to start with. Hopefully it'll get some more updates as the video game's release date gets closer.
