Assassin's Creed is a core childhood Assassin's Creed games without paying at all. Both the free and sale are limited-time events, though, so you'll have to be quick if you want to in on the fun.
The five free games included in Ubisoft's line-up are the classic Assassin's Creed 2, Assassin's Creed Brotherhood, Assassin's Creed Revelations, and Assassin's Creed Valhalla. Valhalla is quite recent as it was only released in 2020, making this the perfect opportunity to experience the Viking-themed game if you haven't yet.
You can play the five Assassin's Creed games for free on PC from Thursday, August 10 to Monday, August 14. You can get each of the five directly from the developer via Ubisoft Connect except for Valhalla, which can be found on the Epic Games Store.
If you're more interested in keeping the series forever, then you can buy each of the Assassin's Creed games during Ubisoft's sale until Thursday, August 17. The sale is on Ubisoft's own storefront rather than on Epic, which means that qualifying purchases will also net you a Ubisoft Wallet bonus.
