Monster Train 2 keeps the three floor vertical defence of the original and adds two card types that change how decks are built. You are defending a Pyre aboard a moving train against waves that climb toward it, and the sequel's Room and Equipment cards mean a run is now shaped as much by what you attach and install as by which units you play.
Boss fights are where Monster Train 2 tests everything you've learned. This guide covers strategies for bosses across all areas, organized by progression order. For general combat techniques, see our combat guide.
