>WW1 with demons
>"mudcore" aesthetics
>no flashy colors
I get the artists try to portray a dark setting that reflects the dirty of WW1, but would be bad to add some flashy colors?
Every pre-modern army had colorful uniforms and armors, or it would be a copy 40k Emperor's Children?

Aside from the aesthetic part, does trench warfare make sense with all the old technology out there? Is it possible?
