The pin isn't tied to the show. If that's a deal-breaker, you'd have to download the custom code from someone on Pinside that has the real actors call-outs.
As far as the game itself, reactions are nowhere near as mixed as they used to be. The game stunk when it was released. Then Lyman dropped in some new code and now the game is incredible.
It can be frustrating, with pretty wide open outlanes, so you have to fight to control the ball almost all the time.
The way the game is coded, players work on building towards a multiball, then bringing in another one to jack up the points. When things line up properly, it's hard to keep track of all that's happening -it's awesome.
Most of the shots are pretty tight, so beginners won't find much flow to the game, but that will improve a little the more you play it. Then, making those tough shots is very rewarding. Cashing in on your "x" kill gives you a one-time shot multiplier, so after you've killed a bunch of zombies, and you decide to try your luck, you either miss an important shot and waste it, or you make a great shot, under pressure and rack up a ton of points.
Watch the PAPA tutorial by Bowen Kierans. That will help explain the rules and strategies.
Just don't expect that any of your games will ever go that well. Ever.
In my opinion, this is one of Sterns very best games to date. Likely to remain that way for awhile with the code that's been done. Lyman is a genius.
