Xbox owners have a fresh batch of titles to dive into as Microsoft rolls out its latest Free Play Days event for August 13 through August 16. The recurring promotion provides Game Pass members with full, time-limited access to a varied selection of premium games, ranging from small indie gems to major open-world releases. While official announcements typically drop alongside the event's launch, developers often give players an early heads-up by confirming their featured games ahead of time.

Understanding the difference between Free Play Days and traditional free-to-play titles is essential for players navigating the storefront. Games such as Fortnite, Apex Legends, and Call of Duty: Warzone cost nothing to download and can be played continuously without any membership requirement. On the flip side, Free Play Days grants temporary full-game access specifically to active Xbox Game Pass Essential, Premium, and Ultimate members, letting subscribers test-drive popular paid releases over the weekend before committing to a purchase.

Headlining this upcoming batch is Sunderfolk, a fantasy tactical RPG created by developer Secret Door. Holding a stellar 93% "Very Positive" score on Steam based on thousands of player reviews, the game provides a novel take on turn-based co-op strategy. Even if strategy RPGs aren't usually your go-to genre, Sunderfolk manages to capture the charm of tabletop adventures like Dungeons & Dragons and translate it cleanly into a video game. An active Game Pass subscription is all you need to join in on the free weekend trial.

The adventure unfolds in a colorful realm populated by creature heroes, where players pick a character class and team up to defend their home village from disaster. What really sets the title apart from typical console games is its unique phone-based control setup: players connect their smartphones or tablets using a mobile app instead of holding standard Xbox controllers. This setup declutters the TV monitor entirely, creating a true board-game vibe where everyone secretly views their cards and skills on their mobile screens while monitoring team battles on the main screen.

Since launching in 2025, Secret Door has continually updated Sunderfolk with extra playable classes and expanded campaign features, cementing its status as an excellent couch co-op title. Naturally, Sunderfolk is just one part of a larger multi-game offering that usually packs three to five titles across different gaming styles. To top it off, Microsoft discounts every featured title during the event, meaning you can grab the full game at a lower price and carry all your save data and earned achievements straight over.
