The collector's pack, named after the Stray Sheep bar from the game itself, is set to cost £54.99 — just a tenner more than the standard game.
The set, which comes packaged inside a pizza box, includes a replica t-shirt, two Stray Sheep themed drinks coasters, and a Catherine poster.
"We wanted to offer Europe's Catherine fans something special and unique, something that was not available before," said Deep Silver's Peter Brolly.
"And with a very competitive price point for the Deluxe edition, we ensure that it's an extremely attractive proposition - just like Catherine herself."
We described the game as a "unique proposition" in our import review published earlier in the year.
