Towards the end of my three hours with Watch Dogs Legion, I came across a moment where my character (a construction worker at the time) stepped towards the ledge of a high building with water below.
The camera shifted to behind my character, the signature Assassin’s Creed music starting playing, and I jumped off the building Assassin’s Creed style into the water. The camera then shifted back and I was free to go on my merry was as if nothing had happened.
I asked Watch Dogs Legion Lead Producer if it was just a cheeky little Easter egg or something more and he confirmed that it was indeed “one of many cheeky nodes in the game”.
