A.R.R.C. is a complex modification for Anno 2070. The goal is to offer many alternatives, but not create elements too powerful. Create a lot of new buildings, research new upgrades and enjoy a better gaming experience.


The new update to version 2.05 is available! Rejoice about the new underwater settlements and all their associated buildings. But beware, these are not cheap and they need an additional oxygen plant to survive. However, they offer a not inconsiderable research bonus. Similarly, it is now possible again to play the campaign and successfully finish it. Over 340 quests in number are added and much more!

Update of Anno 2170 - A.R.R.C  to version 2.05


Since the feedback from the previous beta has been extremely positive, and no serious error occurred, it is time for the final version 2.05. In addition to a few minor bug fixes, new transmission channels for the ornamental buildings and a new channel exclusively for underwater cities are waiting for you.

Underwater City

There are also a few changes in the construction menu, the texture pack “Black Line” was optimized. Brand new textures for a Trade aircraft and the balancing of the Trade aircraft have been improved.

But most important: finally, many buildings have beautiful window pane reflections, making your cities look much more alive! I hope the great effort which was associated with it, has been worthwhile. :)

Have fun wishes you the A.R.R.C. Team!

Should you be prompted to establish a particular building, pay close attention to whether the original icon or that of the texture pack is displayed. (Scenario-Quests usually have the original Icon, accordingly, the building of the texture packs cannot be used).
