4th playable class or alternate ending?

This is not a 4th class. It's one of the wallpapers that were launched for the russian version.

There is alternate ending - it's always the same. And there is no reward for a decent high score, other than bragging rights and such.

Sorry for repeating question but your answer is not clear
I also heard of "no loss ending credits".
So there is alternative ending (even with small difference or text "no losses") or it is always the same?
