That's Not My Neighbor Rank S Guide (Step-by-Step Process)

Attaining Rank S is the foundation for the Employee Of The Month achievement. The key lies in adopting a meticulous, error-free approach.

  1. Preparation Phase: Before any shift, memorize resident profiles from the full list of real residents in That's Not My Neighbor and scan the daily visitor list to anticipate fakes.
  2. ID Verification: Start by cross-checking DDO numbers and photos. Forgeries often have subtle glitches.
  3. Appearance Inspection: Use the zoom feature. Look for fine details like moles on the Sverchzt twins or scars on Roman's chin.
  4. Mandatory Phone Call: Call the apartment every single time. Real residents will be confirmed by roommates or not answer; Doppelgängers often pick themselves up.

Common Pitfalls to Avoid:

How to Get Rank F & Bad Endings 

Sometimes, players seek out the chaotic thrill of Rank F for achievements or just for fun. Achieving this involves deliberately sabotaging your shift:

  • Method 1 (Six Feet Underground): Open the doors to every Doppelganger without question, allowing them to wreak havoc.
  • Method 2 (With A Right To Call): Ruthlessly deny and eliminate all visitors, leading to an empty, silent complex.

These approaches trigger dramatic bad endings, providing a twisted contrast to your perfect runs.
