Game Overview

In "No I'm Not a Human," you face a terrifying scenario where mysterious visitors come to your door during the night. Your survival depends on your ability to identify who is truly human and who is an impostor. The game features over 40 different characters, each with their own characteristics and behaviors that you must analyze carefully.

Confirmed Safe Humans

The game features approximately 10 characters who are reliably human across all playthroughs. These individuals serve as essential allies, particularly for surviving Night 4. You can safely let these characters in without fear.

These confirmed humans are crucial for your survival strategy. Interestingly, certain confirmed humans like the Neighbor's Daughter provide additional benefits—helping them unlocks special achievements and can improve your overall gameplay experience.

Guaranteed Visitors/Impostors

Several characters are consistently dangerous and should never be admitted into your home. These are guaranteed threats across all playthroughs:

Special Night 4 Threat: The Intruder

A unique character called "the Intruder" appears only on Night 4 with a specific question: "Are you alone?"

Randomized Characters

Approximately 30+ characters have variable alignments between playthroughs. These characters require thorough investigation each time you encounter them, as they can be either safe humans or dangerous impostors depending on the playthrough.

For these and 26+ other randomized characters, you must rely on investigation techniques to determine their true nature in each specific playthrough. Never assume based on previous encounters!

Investigation Key Indicators

When examining suspicious visitors, look for these infection markers that reveal an impostor's true nature:

Physical Examination Markers

• Eyes: Bloodshot or discolored eyes indicate infection
• Skin: Fungal growth or unusual discoloration on skin
• Hair: Hairless patches or abnormal hair loss
• Gums: Discolored or diseased-looking gums
• Hands/Fingernails: Unusual hand appearance or fingernail conditions

Photography Investigation

The photography mechanic reveals additional tells that aren't visible to the naked eye:

• Aura Colors: Different colored auras indicate the visitor's true nature
• Supernatural Details: Photos may reveal hidden supernatural characteristics
• Hidden Markers: Certain infection signs only appear in photographs

Strategic Importance & Tips

Success in "No I'm Not a Human" requires maintaining a delicate balance between caution and compassion:

Core Strategic Principles

1. Admit At Least One Human: Letting in at least one confirmed safe human prevents the dangerous Night 4 Intruder encounter. This is crucial for long-term survival.
2. Correctly Identify Impostors: Each correctly identified and rejected impostor prevents household infiltration. Letting in even one impostor can lead to death.
3. Navigate Moral Ambiguity: Some visitors seem harmless despite their true nature. You must make tough decisions knowing that some "threats" might appear sympathetic.

Night-by-Night Strategy

Nights 1-2: Focus on learning character patterns and establishing baseline behaviors. Admit confirmed safe humans early to prevent the Night 4 Intruder.

Night 3: By now you should have a good understanding of investigation techniques. Use this night to perfect your identification methods.

Night 4: The critical night. If you've admitted at least one human, you'll avoid the Intruder. Stay vigilant as the stakes are highest.

Pro Survival Tips

• Document Everything: Keep notes on which characters appeared in previous nights and their characteristics
• Use All Tools: Don't skip investigation steps—examine thoroughly before making decisions
• Trust Your Instincts: If multiple indicators suggest danger, turn them away
• Achievement Hunting: Help the Neighbor's Daughter and other special characters for bonus achievements
• Learn From Deaths: Each failure teaches you about character patterns

Common Mistakes to Avoid

Conclusion

Mastering "No I'm Not a Human" requires a combination of knowledge, investigation skills, and strategic thinking. By understanding the three categories of visitors—confirmed safe humans, guaranteed threats, and randomized characters—you can make informed decisions that keep you alive through all four nights.

Remember the core principles: admit at least one confirmed human to avoid the Night 4 Intruder, thoroughly investigate all randomized characters using multiple methods, and never admit known threats regardless of how they present themselves. With practice and careful attention to detail, you'll develop the instincts needed to survive this psychological horror challenge.

Good luck, and remember: knowing who to trust is everything.
