This is the .PKG file to install watch_dogs. It's the exact file you get from: http://zeus.dl.playstation.net/cdn/EP0001/NPEB01433_00/fqAAXnJQoDpEEqIzotgLimfjmSiykgKDAuLuZAwpPzNmCDXRIagoQdVLMOdGBfXvfIsrJeYSdwNeOuuVGoHYNGGumJMCcQVOIkLNB.pkg

In fact, it's using that as a web seed, so it should be faster to download it from here. Seed anyway, since it speeds it up for everyone.

Use a fix from another release to play.
