ANNO Online is a strategy-based free-to-play browser game that is a spinoff of the Anno series from Ubisoft. Just last week, the new Monuments feature was introduced, which was quite involved and in depth. As a result, the developers from Ubisoft Blue Byte have released a developer diary to help explain all about this new feature.
The Monuments feature “allowed users to resource and build enormous structures, open new tech trees, and help their friends build their own monumental buildings.” For those that may have been a little confused by this new feature, this is an excellent video that should help to explain it a bit further.
