In my ongoing quest to remake all the new stuff from Doom 3 and 4 in Doom 2, decided to see what I can do with Doom 4's supply drone (the little things you get weapon upgrades from). This is just proof-of-concept, sprites are close-enough placeholders from a monster I worked on with Neoworm (I think it was Neoworm, anyway; it's been years), but I don't think he ever finished.
It'll be customizable so map-designers can choose what they want it to drop.
Youtube mangled the video quality a bit. I'm going to have to play around with settings for these.
