In common case, you get get this achievement only between 24 October and 7 November.
But we can "hack" this achievement with changing system time. Worked in 2022!

This guide will work on Linux distro with systemd. I.e. almost on all modern Linux.
Just type systemd --version on terminal. If you see version, you can proceed,


Firstly, you need disable time synchronization. Generally, there are multiple way to sync time on Linux. But common methods: systemd-timesyncd, ntp, chrony. Firstly, determine your method:
1) Check ntp:
ps -Af | grep -i ntp
If you see ntp service, stop it:
systemctl stop ntp
systemctl stop ntpd

2) Check chronyc:
ps -Af | grep chrony
If you see chrony service, stop it:
systemctl stop chronyd

3) Check systemd-timesyncd:
ps -Af | grep timesyncd
If you see timesyncd service, stop it:
systemctl stop systemd-timesyncd.service

After that make sure, that ntp-sync disabled:
timedatectl status

NTP service should be disabled\inactive


After that you can change date.
Very important to change to 2016! If you change to 2022, this "hack" will not work! Not 2021, not 2020. Exactly to 2016 will work!

type this:
timedatectl set-time "2016-10-30 20:31"

And check date:
date:


That is all!
Run the game, ho to "Challenges" and find last "Pumpkin" challenge:


And kill them all!

Super HOT SUPER HOT!

Attention!
Thereafter switch on time sync back! Just replace "stop" to 'start' in command above. Example:
`systemctl start systemd-timesyncd.service`

Time sync should be on! This is very important!

Attention 2!
Internet will not work after change the time. At least https-connections. Close other applications (especially databases!!!) before change time if you have. Do not do it on production systems with application. Just on your home PC. Changing time can break business logic of important production applications if you have.
