Publisher Devolver Digital has confirmed that developer Croteam will reveal a new game next week. The studio from Zagreb, Croatia, is best known for its Serious Sam franchise. The last Serious Sam game, Serious Sam 3: BFE, was released back in 2011.
In 2013 the developer revealed that it was working on Serious Sam 4 after it had started a Humble Bundle promotion to fund the development of the game. The studio went silent ever since the successful campaign had ended.
Just last week the developer had posted a rather cryptic message on the studio's Facebook page stating that "Things are getting serious", most likely hinting at an upcoming Serious Sam 4 reveal. The studio's publisher has also confirmed the announcement through a message on Twitter.
