The goal ofThat’s Not My Neighboris to protect the Neighbors in your building by not letting in any man-eating Doppelgangers, but not everyone is built for the role, and that’s ok! We can’t all be better than Henry — Security Guard of the Month. In fact, if you’re looking to complete every achievement in the game, you won’t want to be better than Henry at all.
‘Worse Than Henry’ is an achievement for being the worst possible security guard you’re able to be, and motivates the overachieving underachiever to be the worst they can be. To become worse than Henry, you’ll need to reach the infamous F Rank.

How To Get The Worse Than Henry Achievement
At the very beginning of your training as a Doorman for the D.D.D, you’ll be introduced to Henry, theonly surviving Doormanof the month, and thus, the best Doorman of the month.
The ‘Worse Than Henry’ achievementfunctions similarlyto the ‘Better Than Henry’ achievement in the sense that you will have to earn one of the most extreme ranks in the game. Understandably, being worse than Henry is theexact oppositeof being better than Henry.

To be worse than Henry, you need tofail so epicallyat your job that youearn F Rankat the end of your playthrough.
Being terrible at your job might sound like an easy accomplishment, but you’ll have todo more than just let everyone goif you want to descend to become the worst Doorman of the month.

How To Get F Rank
To get F Rank you need to be so monumentally bad at being a security guard that youlet in every single Doppelgangerwho comes your way, andnot a single Neighbor.
You will still need toinvestigate convincing Doppelgangers thoroughlyto determine which ones are fakes and which ones really are Neighbors. Only, this time around, you’ll bekilling your Neighbors on purpose.

Youcan’tlet a singleNeighbor go un-murderedand youcan’tturn a singleDoppelganger awayif you want to win F Rank and the ‘Worse Than Henry’ achievement.
Youcannot get F Rank and survivethe playthrough. Obtaining F Rank requires you toget eatenby a Doppelganger.

Tips For Getting F Rank
As we said earlier, you will need toput forth some effortto be the worst Doorman on the planet. You’lluse all of the same toolsyou would use to determine who is and isn’t who they say they are, but instead of welcoming your Neighbors home, you need tocall the D.D.D on them.
Start your day like any other, assess whether each visitor is a Neighbor or a Doppelganger, and dispense judgment accordingly, but this timeimagine that it’s Opposite Day!

Be Thorough
You need tobe just as thoroughas you would on a normal playthrough if you want to achieve F Rank. Neighbors take time to identify, and some Doppelgangers aretoo convincingto do you any favors.
Check and double-checkeach of the provided documents, and make sure touse your judgment. It can be a pain to call every apartment or check each individual I.D. number for accuracy, but the devil really is in the details.

If you accidentallylet a Neighbor inon this playthrough orkill a Doppelgangerwho did a too-convincing job of pretending to be human, you’lllose your chanceat earning F Rank and the ‘Worse Than Henry’ achievement.
Watch The Lock
Considering your job is to be selective about who you do and don’t let into the building, you might assume that the best way to be terrible at that job is tonot do any investigating.
However,letting everyone intothe building by leaving the door permanently unlocked,won’t help you.

With the door unlocked, you’ll have afifty percent accuracy rate. This is because, by leaving the door unlocked, you’reguaranteedto let inevery single Neighborwho deserves entry as well asevery suspicious Doppelganger.
Similarly, youdon’t want to just report every visitorto the D.D.D. either. If you report everyone, you’ll still have only afifty percent success rate, as you’reguaranteed to kill every Doppelgangerthat way while still killing every Neighbor.
Thus, you have to play the game with thesame attention to detailthat you would if you were trying to win.
Call The Apartments
Sincecalling the apartmentsis one of the only ways to suss out convincing Doppelgangers, you shouldstill call apartmentseven when you’re trying to be terrible at your job.
Sometimes, you might believe a Doppelganger or Neighbor’s story about how they forgot their hat or left for an emergency, but if you’re not thorough enough tofact-check them, you could end upkilling or letting in the wrong person.
For an F Rank playthrough, you want to ensure that any time youcall a visitor’s apartmentand getno response, youkill the visitor. No response from the apartment means that the person you are talking to at the window is a Neighbor.
Similarly, if you call an apartment and hear that theNeighbors are already upstairs, you shouldlet in their Doppelgangers. This round, your goal is tosow as much chaos as possible, no matter the consequences.
Talk To Obvious Doppelgangers
Even if youknowthat a Doppelganger is lying, you should stillquestion them. There arehidden achievementsfor meeting certain Doppelgangers and forcatching a Doppelganger red-handed.
You canonlycatch these Doppelgangers bythoroughly questioning themand going through the check list. You never know what detail will trigger a certain achievement like ‘Catch You,’ or special dialogue.
It’s worth talking to even the most obviously sinister characters before you let them into the building.They’ll still kill youat the end if you let them in, but you’ll have amore interesting playthrough.
Other Achievements Possible While Achieving F Rank
One of the great things about achievements in That’s Not My Neighbor, is the fact that in a single playthrough, youcan earn more than one.
The catch is that youcan’t earn every single achievementin asingle playthrough. In the case of the ‘Worse Than Henry’ achievement, you may mostly concurrently earn other negative achievements.
The possible concurrent achievements you can earn alongside ‘Worse Than Henry’ are:‘Work Accident,’ ‘Doppelganger Food,’ ‘Steel Memory,’ ‘Unlikely,’ ‘Open Mind,’ ‘Catch You,’ and ‘Peaches Peaches.’
You can also earn’Collector,' ‘Employee Of The Month,’ and ‘Quarantine’at the same time as ‘Worse Than Henry’ assuming you havemet the game countrequirements for each of these.
It may seem counter-intuitive that you’re able to earn the achievement ‘Catch You’ at the same time as ‘Worse Than Henry,’ but catching a Doppelganger red-handeddoesn’t require killing them. You only have to catch the flaw in their story. Youcan still let them into the building.
Youcannotconcurrently earn any achievement thatrequires you to survivethe playthrough or kill a Doppelganger. Doing so would automaticallyforfeit F Rank.
