Amazon is giving Prime members even more reasons to check out Luna this month, adding three additional games you can claim for free for a limited time. After already expanding April’s free game selection earlier in the month, the service has now boosted the lineup again with three very different experiences—strategy action, cozy farming with a twist, and a puzzle-filled detective story.
First up is Snake Core, a clever reinvention of the classic “Snake” concept. Instead of guiding a single growing line, you control an entire squad in a sci‑fi battle against alien forces. The game plays out across a multi-route map where you choose your path, tackle mission objectives, rescue allies, and take down powerful enemies. It’s a faster, more tactical take on a familiar idea, and it’s built for players who like making decisions on the fly while pushing forward through branching routes.
Next is Monster Harvest, which blends farming, crafting, and monster collecting into one surprisingly addictive loop. You begin by building up your farm—planting crops, gathering resources, and creating useful items—but the big hook comes when you encounter special slimes. These slimes can mutate your crops into creatures known as Planimals, which you can then raise and bring into battles. Seasonal changes also play a role, affecting what you can grow and how your farm develops over time, keeping the routine from getting stale.
Rounding out the trio is Detective Agency: Gray Tie Collector’s Edition, a slower, story-focused mystery adventure. You’ll play as a detective working alongside Detective Amanda and her assistant to investigate a stolen artifact. The case takes you through a variety of locations, from Amsterdam’s canals to ancient ruins, with plenty of hidden-object scenes, puzzles, and mini-games along the way. The Collector’s Edition adds extra locations and additional puzzles, making it the most content-rich version of the game.
Before you plan your weekend gaming, note the deadlines. Monster Harvest and Detective Agency: Gray Tie Collector’s Edition are available to claim until May 20. Snake Core sticks around longer, with a claim deadline of July 15. If any of these sound like your kind of game, make sure to claim them before the offers expire.
