Updated viewmodels from ZM 1.2.1 that are compatible with Zombie Master: Reborn Beta 4 and later.
Yes, you can play online with these and won't get broken animation sequences.
The models have been recompiled and slightly modified in order to work in multiplayer.
That includes kinda new animations and fixed reloading timings (to match the ones on the new models).
Where's Mac10? It will be added to the pack eventually. It just needs less ugly animations to be made for it first (which is in progress).
