Here are all the new unit sprites for 3.14 - namely, the Bogarus units. For other all other unit sprites see
this thread.
The files have names like:
1953_vodyanoy_1.tga -- for the normal sprite
1953_vodyanoy_2.tga -- for the attack sprite
where the 1953 number is the unit id found in the Dom3 DB, or by pressing shift-i on the unit summary screen.
The image files are of the correct format for modding. These files were extracted from the game data files and are pixel perfect. They are not screen captures.
