Corporate Evil: here's a small but fun easter egg that ties together Assassin's Creed 4 with another Ubisoft game—Watch Dogs. You can see this yourself while hacking computers in the Abstergo offices in AC4. Video by MrSkillToKill2.
We'll never make a modern day Assassin's Creed...
So we'll change the name but keep it in the same universe as Assassin's Creed except it will deal with a whole other side of the conflict that has nothing to do with the Animus.
Well played Ubisoft... well played.
