Is there anything else interesting there?
— Unused and outdated icons.
— More detailed sketches of the Necropolis town window.
— Draft versions of the symbols for the Fortress and Necropolis.
— Strange, reddened resource icons.
— Backgrounds for the town hall reputation screens (a removed option).
— A previous version of the menu (static).
— The very first town windows for the Order and Necropolis.
— Early versions of the battle results windows.
— Several completely incomprehensible images.
— 2 versions of artwork featuring Svetlana (now Nastya).
— Fragments from the August demo (08.2010) with a small chat.
— Long-forgotten "CONFLUX" icons.
— Cut silhouettes of a skeleton pikeman and a vampire, but that's not very interesting.
— Unused combat voices and sounds.
That seems to be all the unusual stuff.

Actually, it's a shame. There's all sorts of useless stuff, but it's hard to find what you really need... They could have included it.

I'm digging through the game's archives... There's so much unused content... What prevented them from properly funding the project? It could have been amazing now.
