Anno 1800 is a city-building real-time strategy video game, developed by Blue Byte and published by Ubisoft, and launched on April 16, 2019 in North America. It is the seventh game in the Anno series, and returns to the use of a historical setting following the last two titles, Anno 2070 and Anno 2205, taking place during the Industrial Revolution in the 19th century. Following the previous installment, the game returns to the series' traditional city-building and ocean combat mechanics, but introduces new aspects of gameplay, such as tourism, blueprinting, and the effects of industrialisation influences on island inhabitants.
