According to a new Xbox Wire post, this weekend’s lineup includes Subnautica for Game Pass members, alongside One Piece: Pirate Warriors 4 and Project Motor Racing for all Xbox players, plus a special bonus—Graveyard Keeper is completely free to keep if you claim it in time.

The highlight this weekend is Subnautica, available for Xbox Game Pass Ultimate, Premium, and Essential members from April 9 through April 12. This fan-favorite survival adventure drops players into a mysterious alien ocean world where exploration, crafting, and survival are key.

For all Xbox users, no subscription required, One Piece: Pirate Warriors 4 and Project Motor Racing are also free to play during the same period. One Piece delivers fast-paced anime action with massive enemy battles, while Project Motor Racing offers a revamped racing experience thanks to its latest 2.0 update, featuring improved driving mechanics and a redesigned UI.

One of the biggest perks this weekend is Graveyard Keeper, which is free for all Xbox players to download and keep permanently. The offer runs from April 9 at 9 AM PT through April 13 at 10 AM PT.

This quirky cemetery management simulator blends dark humor with resource management, letting players build and maintain their own graveyard while making morally questionable decisions to grow their business.

How to Download

Players can access these titles by heading to the Xbox Store:

  • On console: Navigate to the Subscriptions tab and find the Free Play Days collection

  • On web: Visit Xbox.com and sign in to install directly

Game Pass membership is required only for Subnautica, while the other titles are open to everyone during the event.

Limited-Time Discounts

If you end up enjoying any of these games, Microsoft is also offering limited-time discounts so you can purchase them and keep your progress, achievements, and Gamerscore intact.

With a mix of survival, racing, anime action, and simulation, this weekend’s Free Play Days lineup offers something for nearly every type of player—so it’s definitely worth clearing some storage space and jumping in.
