Since the last - small - update, a lot has happened to the game. Our 3D artists are creating new assets every day, and as you can see in the image above, the first biome - aka The Town - is a nice view to behold again. Next up will be the sewer level.
Going from one level - or biome - to multiple biomes not only had an impact on the graphic assets of Dieselstörmers. Multiplayer and network code had also had to be rewritten. That's why this feature was deactivated in the Rogue Mission Update. But along with the 3D assets, multiplayer is carefully integrated back into the game - and our programmers are doing their best to have this feature back in our next update.
