🌑 Atomfall Complete Lead Unlock Guide (2025 Edition)

🛠️ Pro Tips for Success
- Always read every log, note, and audio file — even those that seem unrelated.
- Use the Map in your inventory to track “Findings” and Leads in real time.
- Some Leads require multiple visits — e.g., Captain Sims only gives new info after you’ve unlocked another Lead.
- The same location may contain multiple Findings — search thoroughly, especially in basements, attics, and behind false walls.
- Keep your inventory light — too many items can obscure key Findings.
🏁 Final Notes
Atomfall rewards curiosity, patience, and attention to detail. Unlike most RPGs, you don’t unlock Leads through quests — you discover them through investigation.
This guide ensures you’ll:
- Complete the main story (with all 9 essential Leads)
