GoodEngine/HO (File Format)

From Heavy Iron Modding

HO archives are container files used by Heavy Iron Studios in their 7 Havok games. They are used to store assets, which are the resources and objects used to create levels, characters and menus for the games.

Endian

HO archives are stored as big endian in all console versions of each game. Family Guy PC archives are stored as little endian.
