I'm releasing my zombie animation biped for 3dsmax that I used for the Half-Life zombie. It should work great with any type of zomibe or even ogre-like character. It is identical to the biped released by TGC, except for the following changes/additions:
*Two new death sequences
*Slashing with arms animation for melee attacks
*Standard walk replaced with limping walk
Here are the frame details:
Frames 235-259 -limping walk
Frames 2497-2547 - spin and collapse on floor
Frames 2558-2801 - clutch chest and die
Frames 2802-2859 - lunge and slash with arms
