Xbox Free Play Days is back, offering a treat for gamers with Xbox Game Pass Ultimate or Core subscriptions. This weekend, players can enjoy two exciting free games – Killing Floor 2 and Planet Coaster.

Microsoft has announced the lineup for this weekend’s Free Play Days event, giving Xbox Game Pass Ultimate and Xbox Game Pass Core members the opportunity to dive into these games at no cost until Monday, May 20.

Xbox Free Play Days Games (May 16 to May 20)

• Killing Floor 2
• Planet Coaster

While neither of these games is currently part of Game Pass, Planet Coaster was previously available on the service before being removed in 2021. This weekend presents a chance for players to revisit the management sim and complete any outstanding achievements. For those new to Planet Coaster, unlocking all 38 achievements will require approximately 50 hours of gameplay. On the other hand, completing the base list for the fast-paced first-person shooter Killing Floor 2 is estimated to take between 25 and 30 hours.

If you missed out on last weekend’s Free Play Days, there’s still time to enjoy Destiny 2’s Shadowkeep, Beyond Light, and The Witch Queen expansions for free until June 3.
