There's not much more to the Worgen Marine than the title itself - if you wanted an Aliiance unit to offset the Horde's Tauren Marine, then you've come to the right spot.
I'll update the model as needed/necessary.
- Q: Why does the Worgen walk instead of run?
- A: SC2's default animation for movement is the walk animation. There is a running and a walking backward animation if you know how to get to it.
