There are typos within the achievements.
The new Icons were made by Ventpixel and K0vac.
The ' I'll Pass, Thanks' achievement picture is a reference to the Batman slapping Robin meme.
The ' High on the Wings of Caffeine' achievement picture is a reference to the ' Winners Don't Use Drugs' anti-drug slogan.
The ' Ha! I didn't even feel that!' achievement picture appears to be a reference to this picture.
The old 'Look! I'm a Rocket!' achievement icon uses the removed Positronic Grenade, instead of the Frag Grenade.
The old 'Microwave Meal' achievement also uses the legacy version of the Micro H.I.D..
Out of all the SCPs, SCP-079 is not shown in any achievement icon.
SCP-049 and SCP-096 are featured once each, SCP-106 is featured twice and SCP-173 is shown twice with one for its normal model and another with its Christmas model. SCP-939's model from Halloween 2018 has its glowing mouth featured.
In achievements tracking how many Class-D have been killed, there is a special statistic that tracks this number.
This statistic is known as "dboys_killed."
There is an unused achievement called "Roasted", which could be obtained by surviving a hit from a tesla gate as an SCP.
