Start stockpiling rubber sheeting and clean underwear as Amnesia: A Machine for Pigs should arrive some time from April to June, Amnesia creator Frictional Games has revealed. Dear Esther developer thechineseroom is the main force behind this semi-sequel to Frictional's Amnesia: The Dark Descent, taking the horror adventure game into a grimy Victorian industrial world with an unnerving amount of meat-processing machinery.

thechineseroom has sent over "their final version of the game," Frictional said in a blog post, but there's still more to do. "We are testing, tweaking, optimizing, porting, translating and all those things that are part of the process of creating and releasing a game."

A Machine for Pigs was initially slated to launch for Halloween 2012, but kept growing.

"Originally we thought it would be a short, experimental game set in the universe of Amnesia, but thechineseroom had a vision that was bigger than that," Frictional explained. "As their work progressed, the potential for a much greater project emerged. What we ended up with is no longer what we had first imagined, but a fully fledged Amnesia game. A different kind of Amnesia, but definitely not a short experiment."

Here's the trailer from last Halloween again:
