Wow, the rumors and leaks for the new Assassin's Creed have been doing their rounds this year. If Ubisoft had wanted to keep any of it a secret for E3, then they should have kept a tighter lid on the information. Or maybe 'leaking' it before E3 was all part of their stealthy brilliant master plan all along.
The latest to sneak onto the internet is a supposed leak of the main protagonist and the new AC logo. Up until now, we've seen indications that the new title will be called Assassin's Creed: Origins and that it will be set in Ancient Egypt. Comic Book has reportedly received information from sources within Ubisoft pertaining to the new logo and protagonist, with these screenshots as proof.
If this is for real, then the litter of leaks breaking out over media will surely push Ubisoft to make an official announcement before E3, or at least confirm whether the rumors are true or not.
