In Dieselstormers players explore the medieval city of Ravensdale - a place where armor is powered by roaring engines, princesses wield wrenches in oil-stained overalls, and not a single dragon dares to brave the smog-filled sky. That doesn't mean all is well. The inhabitants of Ravensdale must take their city back from a rampaging ork horde. Players will be able to assemble their own weapons by adding and exchanging parts and modify them for their specific needs.

Dieselstormers is the first real multiplayer game by Black Forest Games. Missions and levels are designed for 1 to 4 players while some quests require a high level of teamwork, tactics and strategic skill. Players explore a wide range of different settings where they fight evil bosses and strong monsters in explosive battles utilizing their customized weapons.

German indie games developer Black Forest Games (known for Giana Sisters: Twisted Dreams) received a letter, stating that the Italien fashion brand DIESEL had filed legal opposition to Black Forest's trademark filing of "Dieselstormers". If Dieselstormers, a multiplayer action game out on Steam Early Access, would receive a trademark, it was argued, there would be a "Likelihood of confusion" with the DIESEL brand. The trademark for DIESEL brand covers not only fashion, the company’s main product, but Christmas tree decorations, toothpaste, walking sticks and many others things, among them games.

Since the trademark is now contested by a non-German company the developer will simply wait for a ruling of the “Office for the Harmonization in the Internal Market”, an EU agency. In all probability an understanding will be reached as Black Forest have no intent to create clothing under the Dieselstormers brand — and the "Diesel" part of Dieselstormers refers to the liquid fuel type of the same name and is not a parody of the fashion brand.

Andreas Speer, Managing Director of Black Forest Games, keeps his cool: "The history of the Dieselstormers project is full of challenges. This dispute is simply one more thing to overcome, but we will not be deterred in our will to make a great game."
