On September 4, Amazon Prime Gaming revealed the list of 11 PC titles that active subscribers can download throughout the month, including three games that are now claimable. Users who connect their Amazon Prime and Twitch accounts can now claim PC games, like Sid Meier's Civilization 4: The Complete Edition, at no additional cost.
The PC titles included in Prime Gaming's monthly rotation can then be launched via the Amazon Games app on Windows 10 and 11 operating systems. Alternatively, Prime Gaming's free offers may instead be available via GOG codes or after connecting a Twitch account to the Epic Games Store. An active Amazon Prime subscription, starting at $14.99 per month, is required to claim each Prime Gaming offer while it lasts. The August 2025 Prime Gaming rotation included titles such as Thief: Definitive Edition, FATE: The Traitor Soul, and Civilization 3 Complete for players to claim throughout the month.

Additionally, Dungeons & Dragons: Ravenloft Series allows players to step into a first-person RPG that takes place in a realm based on Ancient Egypt. The third game that is now available as a new Prime Gaming offer is Into The Breach on GOG, a turn-based strategy title from Subset Games, the creators of FTL: Faster Than Light.
