Monster Train 2 just got even bigger. Today, developer Shiny Shoe and publisher Big Fan Games have released the game’s first free content update, Lost Arsenal, giving fans new ways to experiment, expand, and survive aboard the fiery rails.
Already hailed as one of the strongest deckbuilding roguelikes of the year, Monster Train 2 refines the vertical, three-tier combat that made the original a hit while introducing all-new clans, factions, and mechanics. And now, with the Lost Arsenal update, the battlefield is shifting once again.
What’s Inside Lost Arsenal?
The update adds new tools to shake up every run:
- New Room, Equipment, and Spell Clan cards – including clanless cards that expand versatility and strategies across multiple factions.
- Balancing tweaks and improvements – legacy cards from the original Monster Train have been polished to integrate seamlessly with the sequel’s systems.
- Nintendo Switch upgrade – a new unlocked frame rate setting lets Switch 2 owners take full advantage of the system’s improved performance.
The arrival of mysterious rooms and the return of sacred relics have clans on edge. A new threat looms, and the only way forward is to adapt, improvise, and draw your strongest hands yet.
More Than Just New Cards
Beyond today’s update, Shiny Shoe has confirmed that the Monster Train 2 journey is just leaving the station. A full roadmap into 2026 teases new bosses, artifacts, and even a brand-new clan—promising that this roguelike deckbuilder will only get deeper and more chaotic with time.
The Lost Arsenal update also launches alongside the Deluxe Edition, bundling the base game with its soundtrack and digital compendium at a discount. Perfect for newcomers ready to ride the rails for the first time.
