The highly anticipated roguelike deckbuilder Monster Train 2 has taken the gaming world by storm, achieving an impressive player count just days after its release on May 21, 2025. Developed by Shiny Shoe, Monster Train 2 builds upon the success of the original with new card types, Clans, and formidable enemies, delivering a fresh and exhilarating experience for fans.

The sequel continues the epic saga of an unlikely alliance between angels and demons, who must unite to defeat the Titans that have seized control of Heaven. Players navigate through Hell, Heaven, and the Abyss, battling relentless enemies determined to halt their progress. Beyond its captivating gameplay, Monster Train 2 has also launched a thrilling Cult of the Lamb collaboration, allowing players to recruit Cultists into the Legions of Hell.

Within days of its launch, Monster Train 2 has not only earned "Overwhelmingly Positive" reviews on Steam but also reached a peak of 17,914 concurrent players, eclipsing the first game's lifetime peak. This achievement has secured Monster Train 2 a spot in the top 100 of the Steam Charts, a remarkable feat for a new entry in the deckbuilding genre.

Steam reviews overwhelmingly highlight Monster Train 2 as a superior sequel, with players commending its refined gameplay and urging others to purchase it, especially fans of roguelike deckbuilders. Some have even dubbed it one of the best roguelites currently available. Given the genre's rising popularity, Monster Train 2's success is no surprise, further bolstered by fun collaborations with Balatro and Cult of the Lamb at launch, which likely attracted a broader audience.

For returning players, Monster Train 2 offers fresh strategies through new Clans and card types, providing diverse ways to tackle enemies and bosses. Newcomers will appreciate the comprehensive tutorials that guide them through each battle phase while allowing ample room to develop personalized strategies.

Following its successful Cult of the Lamb and Balatro crossovers, Monster Train 2 could explore more collaborations with other indie titles that align with its fantasy theme. A potential Slay the Spire partnership seems fitting, given their shared medieval aesthetic and combat mechanics. Such a move would be timely, especially with Slay the Spire 2 on the horizon.
