📊 Pros & Cons

✅ Pros

  • Zero vanilla changes means it's safe to drop into any existing save.
  • The nuclear reactor repair puzzle sounds like a meaty endgame challenge.
  • 73k downloads with no endorsements yet—clearly people are trying it out.

⚠️ Cons

  • No endorsements yet, so community feedback is thin—you're an early adopter.
  • The description is vague on what the puzzles actually involve, so expect surprises.
  • Compatibility with other overhaul mods is unverified—test before committing.
🎯 Is This For You?

📦 Install:Easy· Under 1 minute

💡 Beginner Tips

  • Since it doesn't touch vanilla, you can add it mid-save, but you'll need to travel to Fulgora to find the new content.
  • The nuclear reactor likely needs a lot of power to repair—stock up on accumulators and solar panels before heading to the moon.
  • Look for wrecks in the ice; they might be hidden under thick layers, so use radar or explore thoroughly.
