...The zombies are, not the game :p
I'm a bit busy and Alpha 5.0 looks way too far for my taste so I had this brilliant idea.
Let's release the work done on 5.0 and call it 4.2.
You will be able to start toying with stats modding for instance... and I'm sure you guys will find enough bugs anyway.
I'll release it soon, hopefully in a few days.
End of post.
