Searching for indie title that looked like alien swarm. Thread

hello guys!

a few months back i stumbled upon a indie game of some eastern europe company that looked a lot like alien swarm, but with a deeper rpg system, more classes and up to 8 player co-op gameplay.
unfortunately i was in a hurry, and i totally forgot to write the name of the game down.
it's been a month now or so and i still haven't found it. can't find anything in my browser or youtube history and now i'm not even sure anymore where i saw it the first time.

one thing i know is that it's unreleased, and probably no playable alpha.

if anyone could help me i would be very thankful!
