Prime members now have 17 new Amazon Luna additions in May, including three new GOG titles with separate claim windows. This guide shows you how to find the new titles, secure them through Luna, and decide which to play first.
The newest batch includes Space Grunts, Palindrome Syndrome: Escape Room, and Hot Brass, all listed as GOG titles, according to Notebookcheck.
Claim Amazon Luna’s Three New Prime Games Before Their Expiration Dates
Amazon has added another three games to Amazon Luna, bringing May’s reported total of new Luna additions to 17 games so far. The three newest Prime-available titles cover different play styles: roguelike tactics, sci-fi escape-room puzzles, and tactical SWAT action.
Here are the three deadlines to prioritize:
| Game | Store label | Claim deadline | Best fit |
|---|---|---|---|
| Palindrome Syndrome: Escape Room | GOG | June 20 | Logic puzzles and sci-fi mystery |
| Hot Brass | GOG | June 24 | Tactical solo or co-op SWAT missions |
| Space Grunts | GOG | August 19 | Fast-paced turn-based roguelike combat |
Analysis: The shortest windows belong to the two June games, so handle those first if you are checking Luna quickly.
Before You Start: Check Prime, Luna Access, and Your Play Setup
You need an active Amazon Prime membership on the Amazon account you plan to use with Luna. Amazon’s own Luna materials say Prime members can access Luna on devices they already own, including Fire TV and tablet devices, smartphones, tablets, web browsers, and select LG and Samsung smart televisions, according to Amazon.
Check three things before you start:
- Account: Use the Amazon account tied to your Prime membership.
- Device: Use a supported Luna access point available to you.
- Controls: For non-GameNight Luna titles, Amazon says games require a controller or mouse and keyboard.
Watch out for name confusion. Amazon Luna is the cloud gaming service. It is unrelated to product leaks with “Luna” in the title, such as MLXIO’s coverage of the €949 Luna Ultra leak showing Insta360 betting big on pro or Insta360 Luna Ultra leaks with a screen that becomes a mic.
Step 1: Sign In With the Amazon Account That Has Prime
Start by signing in to Amazon using the same account that holds your Prime membership. This matters because the offer is tied to Prime gaming benefits, not just a general Amazon login.
If the Luna games do not appear as included or claimable, check whether you are using a secondary account, a different browser profile, or another household profile that is not attached to Prime.
Watch out for: switching devices mid-process. If you start on one device and continue on another, make sure both sessions are using the same Amazon account.
Step 2: Open Amazon Luna and Find the Prime-Available Games
Open Amazon Luna through a supported device or browser route available to you. Amazon positions Luna as part of Prime’s entertainment benefits, and the source material says these games are available for Prime members to download and play through Luna.
Once inside Luna, look for the area where Prime-available games are shown. The exact interface can change, so rely on the current Luna labeling rather than a fixed menu name.
You are looking for these three titles:
- Space Grunts
- Palindrome Syndrome: Escape Room
- Hot Brass
Do not confuse them with earlier May additions. Notebookcheck reports Amazon first added 11 new games at the start of May, then followed with three more titles, and now added this latest batch of three.
Step 3: Check the Deadline Before You Pick a Game
Open each game’s detail page and look for its claim timing before choosing what to play. That keeps the practical task separate from the entertainment choice.
That order is not about quality. It is about avoiding preventable loss, especially with the two June dates arriving before Space Grunts.
Analysis: If you only have time for one quick action, start with the title that has the earliest listed date in Luna.
Step 4: Claim All Three Games Individually
Select one title, open its Luna listing, and use the current claim or add option shown by Amazon. Then repeat the process for the other two games.
Use this checklist:
- Claim Palindrome Syndrome: Escape Room
- Claim Hot Brass
- Claim Space Grunts
- Confirm each title separately after taking the claim action shown in Luna
If a title does not appear where expected, recheck the basics: Prime account, Luna access, and whether the offer is still available.
Step 5: Decide Which New Luna Game to Play First
After claiming, choose based on session type.
Space Grunts is the most combat-driven of the three. It is a fast-paced turn-based roguelike set in 2476, with players controlling elite “Space Grunts” sent to investigate a moon base that stopped responding after sending a distress signal. Character classes include the Leader, Enforcer, and Tech Junky.
Palindrome Syndrome: Escape Room is slower and puzzle-focused. You wake up alone inside a spaceship with no memory of who you are or how you got there. The loop centers on hidden clues, passwords, room investigation, and logic-based puzzles.
Hot Brass is the co-op pick. It supports solo play and co-op for up to four players, putting you in SWAT missions involving hostage rescues, bomb threats, gang arrests, and robberies.
| If you want… | Start with… |
|---|---|
| Short tactical combat runs | Space Grunts |
| Puzzle-solving and mystery | Palindrome Syndrome: Escape Room |
| Co-op tactical action | Hot Brass |
Step 6: Set Reminders for the Next Luna Rotation
Amazon is adding Luna titles in waves this month. Based on the source material, May has already seen multiple drops: 11 games, then three more, then this latest three-game batch.
A monthly Luna check is sensible. Prime game offers rotate, and Notebookcheck’s report shows Amazon is continuing to add titles across the month rather than only in one large drop.
If you use calendar reminders, set them ahead of the listed Luna dates rather than on the final day. That gives you time to deal with account, device, or availability issues before the offer disappears.
Secure the Three New Luna Games in the Right Order
The fastest path is straightforward: sign in with your Prime-linked Amazon account, open Amazon Luna, find Space Grunts, Palindrome Syndrome: Escape Room, and Hot Brass, then use Luna’s current claim option for each listing.
After that, pick based on mood: Palindrome Syndrome: Escape Room for puzzles, Hot Brass for tactical co-op, or Space Grunts for quick roguelike combat. If Amazon keeps adding Luna titles in waves, the useful habit is checking the Prime section regularly enough that new offers do not pass unnoticed.
Key Takeaways
- Prime members have three more Luna games to claim as part of May’s 17 reported additions.
- Two of the new GOG titles expire in June, making them the most urgent to secure.
- The lineup spans puzzle, tactical action, and roguelike gameplay, giving different players a clear starting point.
