To accompany his vegetation footstep sets (very light, light, moderate, heavy, and very heavy), Kevin Fishburne has released a set of sounds for twigsnaps. Again, this is a public domain sound effect set.
In his Twitter message, he noted:
Twigsnap is mixed with vegetation footsteps with probability based on vegetation depth.
As he noted on the previous releases: These are recorded and edited by Santimonia and have been released to the public domain, and may be used for any purpose, including commercial, without restriction.
Sanctimonia is an open source massively multiplayer online role playing game in the spirit of Ultima.
