There are now a few reasons to believe a new Hitman game may be on the way. The official Hitman account sent out a cryptic tweet today that points to some kind of reveal on June 7, which is the same day that publisher Warner Bros. is holding a pre-E3 2018 reveal event.

A tweet from the WB Games account shows a race car with the brand "Hamsun" on it; that could be a reference to the fictitious oil company referenced in Hitman Season 1. A more direct indication that Hitman 2 is coming is that a logo for Hitman 2 was found on WB's official website. So yeah.
