Amazon Luna is rolling into its third week of May with another fresh batch of titles for Prime members. After earlier additions throughout May, this week’s lineup shifts the spotlight toward critically appreciated indie titles offering a mix of tactical action, psychological puzzles, and retro-inspired sci-fi combat. Leading the pack is the intense co-op shooter Hot Brass, joined by the mind-bending Palindrome Syndrome: Escape Room and the roguelike strategy experience Space Grunts.

 

The Second May Drop For Amazon Luna

Headlining this week’s additions is Hot Brass, a fast-paced tactical shooter that has earned praise for its challenging gameplay and strong emphasis on teamwork. Players take control of elite SWAT operatives tasked with defusing hostage situations, breaching dangerous locations, and neutralizing threats with precision. Unlike traditional run-and-gun shooters, Hot Brass rewards careful planning, communication, and split-second decision-making making every mission feel tense and rewarding whether played solo or in co-op.

   

Joining it is Palindrome Syndrome: Escape Room, a sci-fi puzzle experience set aboard an abandoned spaceship where players wake up aboard a spaceship with no memory of how they got there. The game leans into atmospheric storytelling requiring players to solve interconnected puzzles while uncovering fragments of a larger mystery. Its slower pace contrasts sharply with Hot Brass but the clever room designs and unsettling atmosphere have helped it stand out among escape room fans looking for something more immersive and narrative-driven.

   

Closing out today’s drop is Space Grunts, a retro-style roguelike that blends turn-based strategy with fast arcade-inspired action. Set in the year 2471, players are sent to investigate a distressed moon-base filled with aliens, traps, and procedurally generated levels. Every step players take moves the enemies and the environment so the game encourages experimentation through its wide selection of weapons, gadgets, and character builds. Its pixel-art style may look simple at first but underneath is a surprisingly deep and addictive gameplay loop that indie fans have continued to praise over the years.

   

There’s still one final Amazon Luna drop scheduled for next week which will once again bring another batch of three free games for Prime members. Also don’t forget the Luna games available to stream for free if you’re in the region that is supported.

 

How to claim the free GOG code from Prime Gaming?

Although the free codes are claimed on Prime Gaming, you will still need a GOG account as they are only redeemable on the said platform. So after you click ‘Get Game’ from the Prime website, head on over to the GOG code redemption page and click Continue. The game will then be automatically added to your account.
