[PC][2010s] Scifi Diablo Clone

My brain randomly fired some synapses left under a carpet or something and I remembered this game I used to play, help me out if you can, please.

It was a 2D isometric, vaguely Diablo-styled game but set in some kind of sci-fi universe. There were I think only 3 or 4 characters to choose from, one was a female character had some kind of aura or nova based powers. You fought masses of random aliens, with a LOT of fog of war on your main screen.

I know this is fairly thin, and if I remember any details I'll update the post.
