Four games are free to play for Xbox Game Pass Ultimate, Premium and Essential members in this round of Free Play Days: Sumerian Six, Hypnospace Outlaw, Sunderfolk and STUFFED. The event runs from Thursday 12 November to Sunday 15 November.

If you buy a game during the event, Xbox says you keep the Gamerscore and achievements you earned. Discounts and availability can vary by title and region.

Sumerian Six

A real-time tactical stealth game set in WWII. You lead the Enigma Squad, a team of commando scientists, on secret missions against the Third Reich, with ex-member Hans Kammler and a mystical substance called Geiststoff standing in the way.

Hypnospace Outlaw

A ’90s internet simulator where you browse weird and wonderful websites to hunt down wrongdoers, while dodging viruses and adware and keeping an eye on your inbox. The full game is 75% off during Free Play Days.

Sunderfolk

A tactical co-op RPG built around game night. Your phone becomes your guidebook, controller and player sheet, and one copy of the game covers the whole party. The free mobile app is required to play.

STUFFED

A procedurally generated first-person shooter set in a little girl’s dreams. You defend the bedroom door against waves of nightmares, spend points to unlock new map areas and weapons, and can play solo or in up to 4-player online co-op.
