At the start of May, Luna added new games
At the start of May, Amazon Luna added 11 new games to Luna (formerly Prime Gaming), and later followed that up with three more titles. Now, another batch of three games has officially joined Luna, bringing the total number of new additions in May to 17 games so far.
First new addition: Space Grunts
The first new addition is Space Grunts (GOG). This is a fast-paced turn-based roguelike set in the year 2476. Players take control of elite “Space Grunts” sent to investigate a moon base that suddenly stopped responding after sending a distress signal. Players can choose between different character classes, including the Leader, Enforcer, and Tech Junky, each offering unique playstyles and abilities. Throughout the mission, you’ll fight aliens, robots, drones, and other threats while exploring deeper parts of the moon base.
Second new addition: Palindrome Syndrome: Escape Room
The second game joining Luna is Palindrome Syndrome: Escape Room (GOG), a sci-fi puzzle title focused on exploration and mystery. The game begins with players waking up alone inside a spaceship with no memory of who they are or how they got there. The main focus here is solving logic-based puzzles while investigating different rooms throughout the ship. Players must search for hidden clues, decode passwords, interact with objects, and slowly uncover the story behind the mysterious situation.
Final new addition: Hot Brass
The final new addition is Hot Brass (GOG), a tactical SWAT-focused action game that supports both solo play and co-op for up to four players. In the game, players step into the role of elite SWAT operators handling dangerous missions such as hostage rescues, bomb threats, gang arrests, and robberies. The gameplay focuses heavily on strategy and quick decision-making. Players can use different tools and equipment, breach buildings through multiple entry points, and even destroy parts of the environment to gain an advantage.
Deadlines to claim
All three games also have a deadline and must be claimed before it expires. Palindrome Syndrome: Escape Room will remain available to claim until June 20, while Hot Brass’ deadline will expire on June 24. Space Grunts, on the other hand, will remain available until August 19.
