Ubisoft is set to release a DLC for Anno 117 titled Prophecies of Ash on April 23. This expansion introduces Cinis, the largest island in the series, featuring a volcano that adds risk and strategy to city-building. Cinis extends the Latium province and offers various resources, including a new resource called Obsidian for crafting unique items. The DLC will include volcanic mechanics such as eruptions and a bloom phase that affect agricultural productivity. Players can also build a temple dedicated to Vulcan, enhancing mining productivity and fire safety. Anno 117 has received a 'Mixed' rating on Steam due to issues like the use of AI art and perceived incompleteness at launch, but it has achieved the highest launch in the series' history.
