Mix that with Japan's obsession with cosplay (and role-playing), and I can see the unique appeal here. That said, I think that a truly interactive house (Fight back? Heck, yeah!) could be a huge, huge hit in the United States, too, though I agree that the quality and technology of game play would have increase. After all, we, uh, are used to shooting each other over here. :^/
I think here, the weapons would be presented as "lasers" & I could even see the zombies being robot or machine based zombies, as that would draw fewer issues.
But back to the original attraction, it sounds like a cool, scary version of a haunted house.
In regards to 129..., that could be true about the life meter. It just seemed awful convenient that everyone in my group went from green to red at the exact same time, whether they had been close to zombies or not.
Basically, for live shooter games, your options are laser tag and paintball. And paintball's a mess, not to mention potentially painful if players aren't geared up right.
By the way, the phrase "Buzz Lightyear's Zombie Blasters" wins the Internet today.
Ooops, maybe I should copyright that scenario. Or did I just do that by inference?
Obviously, I don't think they believe this in any kind of literal way, but it's an interesting cultural concept.
To me, the allure of killing zombies is the attraction, not the guns itself. In The Walking Dead, the survivors are specifically asked to refrain from using guns if possible to ensure zombies are NOT attracted to the noise. Noise is a negative. A survivor is better off using a knife or prop.
It's like how some people are attracted to what they're not supposed to have. This "game" allows people to do that, along with simulating reality just like some video games do.
I don't see this flying in the US because all it would take is one idiot to ruin it for everyone by physically attacking an actor.
It's different than regular horror/ scare trails and hotels/ haunted houses. The visitors don't do anything... in this Biohazard one, you fight back with laser guns.
