Ubisoft’s Watch Dogs is easily one of the most anticipated “next-gen" titles to hit this year, and like you do these days, they’ve got a companion app along side the game ready for launch. It’s called ctOS Mobile (Free) and you don’t even need Watch Dogs to fiddle with it.

The core of the game slash app slash whatever you want to call it is for mobile players to play against PC/console players and vice versa. In either race or free ride modes, the person playing Watch Dogs proper races around avoiding obstacles. Where do these obstacles come from? The ctOS Mobile player who “hacks" in to the city and views a top-down map where they can do things like dispatch police, send an attack helicopter, and set up other various obstacles.

You’ll need a Uplay account to play, and using the Uplay system you can play with friends or total internet strangers. Cooler yet, this is all totally cross platform so you can be playing ctOS Mobile with people playing on any platform Watch Dogs is available on. Additionally, both Watch Dogs and ctOS Mobile have their own in-game progression systems that piggy back off each other in subtle ways, so to get the full Watch Dogs experience you’re going to need to at least dabble in the mobile side.
