Itweas has released his Wolf addon. It comes with a demo mission. I haven't tried it myself but people seem to be impressed, particularly with the animation and scripting.

*note - at time of this post the above link goes to the front page news which features the addon. As such, in a couple of days / weeks it may not be there so just search the site for the addon.

"Machine gun, yeah,
Tearin' my body all apart.
Evil man make me kill ya.
Evil man make you kill me.
Evil man make me kill you,
Even though were only famlies apart." -- Jimi Hendrix - Machine Gun
