FootstepTable Asset
The footsteptable only exists on Black Ops 2 and very clearly contains footstep information, however the particular type of information held is currently unknown. Refer to the surfaceNames_t on the weapon page for a list of the surface names, there is one FootstepSurface entry for each one.
struct FootstepSurface
{
char unknown[0x1C];
};
struct FootstepTable
{
const char * name;
FootstepSurface surfaces[0x20];
};
