* [[HNM (1)]] Improved version, with typed chunks, dynamic palettes and (optional) soundtrack.
HNM and HNM4 format animations are used in games like Commander Blood and Lost Eden. One of the differences is that HNM4 animations don't seem to contain an audio track, while the HNM ones do contain uncompressed PCM audio data.

Both HNM and HNM4 are palette-based formats.
* [[HNM4 (A)]] Hi-resolution format spin-off, used in ALIENS game. While all file tags indicates genuine HNM4, interframe (de)compression is not compatible.
 
* [[UBB]] Another hi-resolution spin-off, first appeared in MegaRace 2 game. Same file structure as in HNM4, but completely reworked codec.
HNM6 is used by newer Cryo games made in the late 1990ies, e.g. China: The Forbidden City and probably the Atlantis games. The audio format in these animations is similar to Cryo's Apc audio format.
