This is the dangerous part. While "FitGirl" is a trusted name, many malicious actors upload fake "FitGirl" repacks containing ransomware, miners, or trojans.
The of The Hong Kong Massacre is a popular choice for users looking for a significantly compressed version of the game that retains all original features.
FitGirl repacks are static. To update, you would need to download a new repack of the updated version or find separate update patches (rare). The last official game update was in 2019, so you aren’t missing much.
