Tags filenames and locations:

For Myth 2:
Myth II/local/observer constants/observer physics constants

For Myth TFL:
Myth TFL/tags/Local/obpc/obpc

===============================================================================

To edit, open Fear and go to:

observer constants -->	observer physics constants (obpc)

===============================================================================
Parallel Velocity:	camera up / down
Orthogonal Velocity:	camera left / right
Vertical Velocity:	unknown, probably a disabled dimension of camera motion

Yaw Velocity:		rotate camera (a & d keys)
Pitch Velocity:		unknown, probably related to the Vertical Velocity
Orbit Velocity:		orbit camera (q & e keys)

Zoom Velocity:		Zooming camera in and out
===============================================================================

Both Myth TFL and Myth 2 have an identical observer physics constants tag from
hex offset 64 onward. So an observer physics constants (obpc) file produced by
Fear for Myth II can be used with Myth TFL as long as the header from offset
63 and earlier has been overwritten by the one in the original TFL obpc tag. 
The reverse is probably also true.
