Originally, Watch Dogs 2 was going to be given away through Ubisoft's online conference Forward. As you might imagine, the moment the Forward stream went online was also the moment the giveaway collapsed under the sheer weight of all the people trying to get themselves a copy.
In order to correct this little issue, as well as give people another chance to grab Watch Dogs 2, Ubisoft has now launched a less time-pressured giveaway. Simply head on over to the Ubisoft website, log in or create a new account, and Watch Dogs 2 will be added to your library in no time flat.
Speaking of time, I'm afraid I have no idea how long this new giveaway will last. So if you're even remotely interested in Watch Dogs 2, I would suggest claiming yourself a copy sooner rather than later, lest you end up missing your chance.
Have fun, and if you're curious about what sort of announcements you missed from the Forward stream, you can check out the big reveals over at the official website.
