Monster Train is a roguelike deck-building game developed by American studio Shiny Shoe and published by Good Shepherd Entertainment.

A sequel, Monster Train 2, is planned for a 2025 release by Big Fan Games, a label of Devolver Digital who acquired Good Shepherd Entertainment.

[6] Dan Stapleton, from IGN, wrote that the game is "a ticket to dozens – if not hundreds – of hours of challenging and surprising roguelike deckbuilding runs, thanks in large part to its mechanically diverse set of decks and the way they interact with each other when combined in different ways", and in his verdict, scored the game 9/10.

[4] Reviewing the Nintendo Switch version, titled Monster Train First Class, Waselenchuk of COGconnected praised the extensive amount of enemies and cards available; on the other hand, the author lamented the lack of touch screen functionality for the game: "I think many would agree; card games are often the ones that benefit the most from a touch screen".

[10] Monster Train 2 was announced in February 2025, with a planned 2025 release for the Nintendo Switch, PlayStation 5, Windows, and Xbox Series X/S.
