Biters/Zergs both leave corpse graphics that decay over time whereas terran marines and many other infantry units seem to just instantly vanish. Not a big problem though a little weird when the other races do this. Otherwise very nice mod, been waiting for hostile terrans to pair with the other starcraft races

Oh that'll be the animation timings. I'll ask Heyqule about it. Currently Factorio actually doesn't have decaying corpse animations. It has the death animation. In the official expansion they're working on apparently it will have the ability for us modders to add actual corpse animations.
