Mods extend Monster Train 2’s replayability beyond vanilla. This guide covers mods that improve the core experience without gimmicks or power creep. Focus is quality-of-life, balance fixes, and smart expansions for serious players.
These work great with builds from our Monster train 2 best builds guide and endless strategies from our Endless mode guide.
QoL mods that actually matter
Train capacity extended
What it does: Adds 1-2 extra slots per floor (configurable).
Why it works:
Vanilla capacity cramps late-game scaling builds. This gives breathing room for engines without bad positioning.
Best for: Funguy swarms, banished frontlines.
Smart undo
What it does: Extends undo to stasis/unstable interactions.
Why it works:
Vanilla undo misses key moments. This lets you test positioning freely – perfect for echoes mutators.
Best for: All builds, endless experimentation.
Deck visualizer
What it does: Clean deck overview with mana curve and synergies.
Why it works:
Vanilla deck screen gets messy at 20+ cards. Spot bloat early.
Best for: Deckbuilding runs.
Balance mods that fix issues
Fair mutator balance
What it does: Rebalances 20+ swingy echoes mutators.
Why it works:
Some mutators punish builds unfairly. This makes endless more skill-based.
Best for: High covenant players.
Clan parity patch
What it does: Buffs c/d-tier clans (umbra, awoken).
Why it works:
Weak clans become playable without buffing s-tier dominance.
Best for: Tired of lazarus/underlegion meta.
Content mods worth your time
Lost arsenal expansion
What it does: 50+ community-designed neutral cards.
Why it works:
Fits vanilla philosophy. Fresh synergies, no balance breaks.
Best for: Endless mode variety.
Echoes mutator remix
What it does: 30 balanced mutator variants.
Why it works:
Vanilla mutators overtuned. These play cleaner long-term.
Best for: Endless veterans.
