![Alien Grey's "The Basher"]()
This is The Basher, it's the Hammer trap that I used in Alien Grey Cow Abduction2,
I have included a Non-animated Basher, and a Key frame animated Basher, so one can be used as a prop just for background, and a Basher for animation that has two individual Hammer arms that can be animated, you should be able to see how it's animated in the key frame timeline.
