A parody trailer of Watch Dogs has been created using Grand Theft Auto IV and looks pretty damn good. There have been many comparisons between the open world of Grand Theft Auto and the dark future of the hackable Chicago from Watch Dogs.
Unfortunately this trailer wasn't made in the more recent Grand Theft Auto V so viewers could get a better comparison. The trailer was created instead using the Grand Theft Auto IV: Watch_Dogs mod. A user created mod for the classic Rockstar Games' title available on PC.
Check out a side by side comparison of the two trailers here and hit up our review of Watch Dogs.
