Monster Train 2’s New Undo Feature: How to Salvage Bad Early Decisions

Misplaced a unit? Played the wrong card? Monster Train 2’s new Undo feature lets you correct mistakes without restarting a run—here’s how to use it like a pro.


🔄 Introduction: A Lifesaver for New (and Veteran) Players

One of the most requested features is finally here: the Undo button. Unlike the original Monster Train, where one misclick could doom your run, Monster Train 2 lets you rewind mistakes instantly—no restarts required.

This guide covers:

✅ How the Undo feature works
✅ When to use it (and when not to)
✅ Pro strategies to maximize it
✅ How it compares to Monster Train 1's restart workaround

Note: Undo doesn’t penalize you. But if you’re a purist, a “No Undo” stamp offers bragging rights!


🛠️ How the Undo Feature Works

  • Undo Turn: Resets all actions in the current turn—replay cards, reposition units, or rethink your plan.

  • Restart Battle: Resets the entire battle—great for major errors.

  • No Penalties: Doesn’t affect achievements, unlocks, or progression.

Example: Accidentally placed your Fel on the wrong floor? Undo and fix it before enemies attack.


🧠 When to Use the Undo Feature

1. Misplaced Units

  • Problem: You left your Pyre exposed by misplacing your tank.

  • Fix: Undo and place them on the correct floor.

2. Card Misplays

  • Problem: You used a key spell on a weak enemy.

  • Fix: Undo and save it for the boss wave.

3. Testing Interactions

  • Problem: Not sure how a new mechanic works?

  • Fix: Undo lets you experiment without consequences (e.g., Plague Doctor’s Unstable explosion timing).


🚫 When Not to Use It

  • Over-Reliance: Constant undos can slow gameplay and kill momentum.

  • Challenge Runs: Some players prefer “ironman” mode—no undos, high risk, high reward.


💡 Pro Tips for Strategic Undoing

  • Boss Fight Tests: Try different placements vs. Crystalclock or other major threats.

  • Synergy Experiments: Mix risky combos like Valor stacking + Bloodsoaked Arena freely.

  • Path Optimization: Undo helps preview choices like gold vs. unit upgrades before locking in.
