mass drop mobs?

[Woodiex3]

it appears that only appears that zombies and below seem to have the occasional mass drop mobs, nothing higher not a biggy but always nice to have.

I'm yet to have a mass drop I remember when you'd kill a zombie on Euro Mir and it would mass drop and if it got back up it would mass drop again, up to atleast 3 or 4 times, was funny lol
