Video games are not built in a day. In the process of work, they acquire various details and the final versions are very different from the original ones. Now you can look at the test build of Assassin's Creed
The Internet Archive published a selection of gameplay recordings from early versions of games in the Assassin's Creed series. They were uploaded by a user under the nickname TheSUNYPurchaseSunniShia.
There are materials available for games such as Assassin's Creed 3, Assassin's Creed 4 Black Flag, Assassin's Creed Syndicate and Assassin's Creed Origins. Most of the recordings were made during the active stages of development – at least a couple of years before the full release. .
