exploding monsters, like Serious Sam
Ok thx, Poom I was a little surprised, but I see what you're getting at with the pic of the Cacodemon from Doom3. Yeah come to think, I liked doom2 monsters, nice variety. Serious Sam got too weird, but besides that repetitive for me.
There is some monsters in KF actors area that aren't used in the game which you may be interested in looking at. Although Poom, except for your pic of the cacodemon I have trouble visualizing your concepts as terrifying beasts.
