17 hours ago, the official Twitter account for Mafia (the game, not the crime syndicate, you dingus) tweeted just that: Family.
It is unknown whether the cryptic tweet was scheduled to coincide with International Mother's Day, but it seems unlikely given the lack of context nor acknowledgement of past years' celebrations.
That means a new title is probably on its way (don't take our word for it - after all, we only have one word to draw our conclusions from).
We don't whether it will be the next installment of the franchise or simply a remaster of a previous title - if the Twitter comments are anything to go by, a remake of Mafia II seems to be in good demand.
Either way, we'll have to wait until more details are officially revealed in the coming days to find out more.
