Quoted from TomGWI:Just because they are in the same field doesn't mean they can't help each other out. I don't think there relationship will change just because they are both making pinball machines.
This makes sense, but at the same time it seems like bad form to announce a game with the same theme (zombies) at the same time BHZA is being developed. The fact that the BHZA principals are involved in BOTH projects makes it even more odd, in my opinion.
