Four games are free to play this weekend for Xbox Game Pass Ultimate, Premium and Essential members: Sumerian Six, Hypnospace Outlaw, Sunderfolk and STUFFED. According to Xbox Wire, the Free Play Days window runs from Thursday, November 12 until Sunday, November 15.

Free Play Days lets members install selected games and try them without buying them. This round covers a World War II stealth tactics game, a ’90s internet simulator, a co-op RPG played with phones and a first-person shooter set in a child’s dreams.

What is in this week’s Free Play Days lineup?

Here is what each game is, using the descriptions Xbox Wire gives:

  • Sumerian Six (Crunching Koalas): a real-time tactical stealth adventure set in WWII
  • Hypnospace Outlaw (No More Robots): a ’90s internet simulator, listed for console and PC
  • Sunderfolk (Dreamhaven): a tactical co-op RPG built around game night
  • STUFFED (Amplified Games): a procedurally generated first-person shooter with online co-op

What do you actually play in each game?

In Sumerian Six, you lead the Enigma Squad, a team of commandos made up of scientists who carry out secret missions against the Third Reich. Xbox Wire says the squad is trying to stop ex-member Hans Kammler’s plans involving a mystical substance called Geiststoff.

Hypnospace Outlaw has you browse the strange websites of Hypnospace to track down wrongdoers. Along the way you keep an eye on your inbox, avoid viruses and adware, and download apps that may or may not be useful, according to the listing.

Sunderfolk is built for a shared adventure. Xbox Wire says your phone becomes your guidebook, controller and player sheet, and that one copy of the game is enough for the whole party. The listing notes that the free mobile app is required to play.

STUFFED takes place in the dreams of a little girl. You defend your owner’s bedroom door against waves of nightmares, earn points to unlock new map areas and weapons, and can play solo or with up to 4 players online.

How do you start playing?

Xbox Wire lists these steps:

  • Find each game on its details page on Xbox.com. The link leads to the Microsoft Store, where you must be signed in to see the install option that comes with your Game Pass membership.
  • On console, open the Subscriptions tab in the Xbox Store and go down to the Free Play Days collection on Xbox One and Xbox Series X|S.

If you decide to keep a game, buying it during the event lets you continue playing and keep the Gamerscore and achievements you earned, according to Xbox Wire. The post adds that discounts, percentages and title availability may vary by title and region.

Prices

Xbox Wire lists these prices next to each game, shown with a dollar sign. The English-language page does not name a country, so check your own Xbox or Microsoft Store listing for the price where you live.

  • Sumerian Six: $29.99
  • Hypnospace Outlaw: $4.99, down from $19.99, and Xbox Wire describes the full game as 75% off
  • Sunderfolk: $49.99
  • STUFFED: $12.49

Sunderfolk and STUFFED are marked with a Free Trial label on the page. Only Hypnospace Outlaw is given a named discount in the text.

Who it suits

Players who like strategy and stealth have a clear pick in Sumerian Six. It is a real-time tactical game, so expect to plan around a small team rather than rush in.

People who enjoy quirky, story-driven exploration should try Hypnospace Outlaw. It is about browsing, reading and solving, and the discount means it is the cheapest of the four to keep if you like it.

Groups of friends or family are the audience Xbox Wire names for Sunderfolk, since one copy covers the whole party and phones act as controllers. Check that everyone can install the mobile app first.

Shooter fans who want a short co-op session can try STUFFED, which supports up to 4 players online, or play alone against endless waves.

What is not known

The Xbox Wire post does not say which platforms each game supports beyond the Hypnospace Outlaw console and PC note, and it does not give a country for its prices. It also does not say what happens to Game Pass membership requirements after the weekend. Check each game page on Xbox.com before the event ends on Sunday, November 15, and read Xbox Wire for the next Free Play Days.
