Watch Dogs is now out; here's our Watch Dogs review.
Watch Dogs' multiplayer is somewhere between Dark Souls' phantom invasions and Assassin's Creed's "the enemy could be anywhere" approach.
Ubisoft's released a video breaking down the three multiplayer modes, with invasions, mobile play and team-based shenanigans. All taking place in the same space as the single-player campaign.
The invasion stuff remains the most tempting mode, with paranoid hunting giving way to explosive car chases.
Can't say I imagine being the mobile player in the race mode being all that fun, staring at roap. But being the driver, facing the obstacles laid out by another hacker, that sounds a bit spiffy.
