The player meets a number of companions during the game, and can strengthen their relationship with them by battling alongside them, completing their quests, and talking to them at a campfire while resting. The player's character attempts to return to their home as they are helped by other stranded people who are also stuck on the island. The plot of the game follows the player's character as they wake up on the beach of New Wirral, which they were transported to from Earth. The game includes a permadeath mode (similar to Pokémon Nuzlocke rules), where beasts that are defeated permanently die in the playthrough, and a map randomizer, to increase replayability. The player can also find hidden chests and puzzles by walking around the open world and stumbling on them. The player can receive quests from people in Harbourtown and also can receive tips on where to go next. Recording certain types of monsters give the player's character more moves they can use outside of combat to explore the island. New Wirral, the game's overworld, is an open world. There are 120 monsters featured in the game, but there are also over 14,000 fusions. Any of the game's monsters can be "fused" during combat temporarily into another monster. Different monsters have different status attacks and elemental strengths and weaknesses, which can have wide-ranging consequences (e.g., a lightning-type attack will vitrify an earth-type monster, turning it into a glass-type). Combat uses a number of debuffs and thinks critically about how different elements would react to one another when using different moves. Recording beasts from the island is an integral part of gameplay.


The player receives experience points instead of the beasts, meaning that players provide base stats that beasts then add to, providing freedom to try out different setups. Beasts have hit points that determine if they can be used, and the player's character has their own health bar, which once reaching zero, means that the player is sent back to Harbourtown. During battles, each beast can use attacks that are assigned with stickers, which can be transferred between different beasts. The game eschews the random encounter format of early Pokémon games, and all beasts are visible in the overworld. The game initially offers the choice between "spooky or sweet" for their first beast choice, and unlike in Pokémon, the main character is able to transform into the beasts in order to battle.

The player can use their beasts to battle other beasts. The game is played in a third-person view, overhead perspective and consist of three basic screens: an overworld on the island of New Wirral, where the player was transported to a side-view battle screen and a menu interface in the form of a cassette player, where the player can configure their beasts, items, and settings. The battle system of the game involves turn-based attacks with beasts that the player and their companion have transformed into.Ĭassette Beasts is a monster-taming game that bears a number of similarities to the Pokémon video game series.
