The August 22 2005 build, also known as the zap_test build, is an unreleased build of Sly 3: Honor Among Thieves. Not much is known about it aside from what is shown in a low-resolution video posted in 2006.
Notable Features
The build includes an alpha test map which is used to test different kinds of damage. The terrain is untextured and made of basic geometry.
The test level features a prototype guard, which is a modified Sly 2 rat swarmer holding a cobra from India.
It has a debug menu, and error messages sometimes appear at the top of the screen.
