Cassette Beasts is free on the Epic Games Store for a limited time, with players able to claim it until December 28.

Cassette Beasts approaches the creature-collection idea from a different angle: players transform into monsters they've recorded on cassette tapes, rather than catching them in the wild. The game adds online co-op and a music-driven battle UI navigated through an in-game cassette player. PC Gamer's Lauren Morton wrote about the title in 2023, describing it as 'a pretty sick Pokémon remix' and noting its nonstandard element types like plastic, glass, and glitter.

Even with those distinctive mechanics, Cassette Beasts remains active in the indie space, with its most recent major update arriving in April this year, and by November it had crossed 1.1 million units sold.

From a deals perspective, Cassette Beasts provides a cost-free entry into a distinct indie creature-collector space. The combination of online co-op, cassette-recorded monsters, and a music-driven battle UI makes it a notable option for players seeking something different from the major franchises.
