About Us

Thing Trunk is an independent gamedev studio founded by 3 guys, who are known for engineering their games to their fullest: Maciej Biedrzycki (co-founder of Codeminion), Konstanty Kalicki, and Filip Starzyński (founders of Twin Bottles).

Having created many successful games at their previous companies (most notably Saqqarah, Magic Match, Brunhilda, Phantasmat) and a few unintended flops (let’s not put names here) they quickly became disappointed with the miring trends in the casual games market. They scrapped their former brands and together founded Thing Trunk to focus solely on the ambitious Return 2 Games idea.


Book of Demons is the first installment in the Return 2 Games series. True to the origins of the hack&slash genre, Book of Demons tells the universal story of good vs evil, of a hero’s quest to save the world from the ultimate devilry.

In development

A spinoff of Book of Demons, Hellcard is a roguelike deckbuilder with Singleplayer and Multiplayer modes, allowing you to beat the Archdemon with your friends. Exploring paper dungeons alone can be dangerous, so gather your party before venturing forth!

Book of Aliens is the upcoming second installment in the Return 2 Games series. With the Earth threatened by an invasion, you need to lead an agency of scientists and military agents to eliminate the alien threat. Book of Aliens is a tactical strategy game and a tribute to MicroProse’ UFO: Enemy Unknown.
