A continuation of Doug Muir's original Bronze Age New World TL concept from the 2000s, this timeline was started by Hnau in 2011 and lasted until 2012, when it went on hiatus. The 2.0 was intended as a remake and expansion of the original project, even though it didn't get particularly far.
You can find it here. There's also a chapter and map guide available below.

ChugachMtnBlues' timelines Bronze Age New World Alaska and Bronze Age New World: Empire of the Steppe, are not spinoffs of this timeline. Rather, they are spinoffs within the continuity of the original timeline created by Doug Muir.
