We mixed a lot of enemies from all doom games because there were so many cool demons and monsters that we couldn´t just stay only on the first two games. Also we think the concept of “demaking” a game is very interesting. Reversing aspects of, for example a cacodemon to make it cute or grabbing an ultra detailed and scary character like a Summoner and make it 60 pixels tall was endlessly entertaining.
Of course, while making all this sprites I always had theirs very-hi-res counterparts near by. I actually bought the Doom 4 art book only to have a legit reference guide to make my silly pixelart.
I used the concept art for everything from colors to ides for repeating tiles for backgrounds and floors.
And here are some examples of the current sprites on MiniDoom 2 vs their original 3d hi-res inspirations:
EDIT: in case you are a person or robot from google coming to review this page for “shocking content”,.. we know Revenants and Hell Knights can be very spooky, but let let us assure you, they don’t REALLY exist, also, this are not actual photos. kthxbye!
