I noticed in the Game installers and updates download section that Assault Spy was version "V1.3".

However in the patch section there is a patch to take the game from the current version "V1.3" to "V1.3 Test3".

What is the "1.3 Test3" version of the game?

Same question

Assault Spy has been updated from version "1.3 Test3" to "1.3(A)".

So the mystery of Test3 remains unsolved but the good news is the game is being kept up to date.
