When you see the term "REPACK" associated with The Division 2 , it refers to a highly compressed version of the game files.

Because the official version requires constant server validation, REPACKs for this specific title often require "fake server" emulators or custom host files. This is a breeding ground for malware, keyloggers, and cryptocurrency miners. The compression tools used to make the "REPACK" small can also hide trojans that your standard antivirus won't detect for weeks.
