3ds max prototype chestburster - PROTOTYPE CHESTBURSTER (9 of 11) by MasterRavager

Like I said, this is a prototype, which means that not much effort was put into making them. I have equipped them with bones and poses for you to try out, however no textures have been added.
This particular model is the Alien Chestburster from the ALIEN series. They are ALL (or I believe they are all) v15.0, so if you do not have that version of Animation Master they will not work. They should be v13.0, but the tweaking of their poses left them to be the latest version.
