Reddit user Codeboy1 first uploaded the photo of what looks to be a Dead Rising 4 poster, claiming that he had put it together at work. Another user later came forward to share a screen that they claimed was from the game (that post, however, has since been removed).
This Gen Gaming later posted a series of photos that included a logo and a screenshot depicting supposed gameplay. They also reported on a possible reveal for the game earlier in the week after a post on NeoGAF claimed it was coming.
If true, this will be the first new title in the series since Dead Rising 3, which debuted in 2013 as an exclusive launch title for the Xbox One. That game was also announced during the Microsoft E3 presser in 2013.
