This is from a game the artist is working on. Tech demo here:

^ What kind of game is that?

It's a 3d cell shaded monster exterminating game. That particular demo looks like it's showing off a quest system, in which you take a quest then shoot all the monsters to complete it.

Interesting. I would like to play the full version in the future. Say who do you swap characters?
