Evaluation

Cassette Beasts launched on April 26, 2023 and has received a steady stream of major content updates since then. The post-launch content history includes: the Pier of the Unknown paid expansion (October 4, 2023), the free Multiplayer Update (May 20, 2024), the free Gauntlet Update v1.7 with the Fashion Pack cosmetic DLC (November 20, 2024), and the free Sunshine Update v1.8 with a new companion storyline, new monsters, and the Wings Pack cosmetic DLC (April 7, 2025). All seven DLC items listed on the store are marked as released, with the most recent being the Acoustic Sessions soundtrack DLC on April 3, 2025. The most significant signal about the game's future direction comes from two posts in 2026. On May 19, 2026, Bytten Studio published an anniversary zine and referenced "the next project from Bytten Studio" — framing Cassette Beasts as a chapter the studio is moving on from. Then on June 7, 2026, the studio formally announced Cassette Beasts 2002, a sequel, at the PC Gaming Showcase. This announcement, combined with no roadmap or hints of further content for the original game, indicates that development focus has shifted fully to the sequel. The Sunshine Update (April 7, 2025) appears to represent the final major content addition to the original game, and all announced content has shipped. There are no unreleased DLC entries, no outstanding roadmap commitments, and no developer statements indicating further updates are planned for this title.

About this game

Adventure. Battle. Transform.

Collect awesome monsters to use during turn-based battles in this open-world RPG. Combine any two monster forms using Cassette Beasts’ Fusion System to create unique and powerful new ones!

Welcome to New Wirral, a remote island inhabited by strange creatures you’ve only dreamed of, nightmares you hopefully haven’t, and a cast of brave folks who use cassette tapes to transform for battle. To find a way home you’ll need to explore every inch of the island, and record monsters to your trusty cassette tapes to gain their abilities!

Transform into monsters...using retro cassette tapes?!

Faced with the constant threat of monster attacks, the residents of Harbourtown, New Wirral choose to fight fire with fire. Record a monster to tape, then play it back to take on its form for battle!

Fuse monster forms!

Getting close to your companion has benefits–while transformed you can combine your strengths to gain the upper hand in battle! Any two monster forms can be fused to produce unique, fully-animated new fusion forms.

Explore a rich open world

Certain monster abilities can be used in human form. You’ll need these to help you get around, solve puzzles, and locate dungeons. Glide, fly, swim, climb, dash, or turn magnetic! Take on the Gauntlet – a never-ending battle mode where you’ll face fearsome enemies for precious material and glory!

Travel alongside a diverse cast of human companions

Never fight alone! Form bonds, spend time together, and help your selected partner complete personal goals to become a better team. The strength of your relationship determines how well you’re able to fuse!

Master a deep battle system

Take advantage of elemental chemistry to apply extra buffs or debuffs alongside your attack, or even alter your opponent’s elemental type!
