Just the other day, Ubisoft confirmed the existence of Assassin's Creed: Anthology, a bundle that includes all five titles in the series that have launched thus far. Aside from confirmation that it actually exists, the publisher didn't provide any additional details.
However, today Ubi has shed light on the compilation, revealing that it's set to launch in Europe exclusively through Amazon on November 29th and on November 30th in the UK for £119.99. Unfortunately, there are no plans to bring AC: Anthology to North America.
The package will include all five games, all DLC and a Season Pass for Assassin's Creed III.
