On the official Twitter account, Undead Labs - developers of the third person open world stealth zombie-survival horror, Stay of Decay - said that they will announce a new project next Monday.
"We're announcing a game on Monday that has nothing to do with State of Decay."
But Undead Labs have new ideas for this new project, that it hasn't anything in common with the previous game, as they said later:
"It is not a zombie game. Like... not at all a zombie game. More than that, I cannot say."
And they confirmed that later again:
"No zombies, no Microsoft. AND NO MORE HINTS."
Obviously, we're curious to see what the game is about. We have to wait Monday to know more details.
