According to ESRB, this game contains: Blood and Gore, Violence
Parents will want to approach House Of The Dead III with caution. The game is designed around the idea that the players blasts away at a bunch of zombies—most of whom still look decidedly human. In an attempt to appease parents, Sega and Wow Entertainment have made it so that the blood can be switched from red to green, but the gore and violence is still quite graphic.
Fans of light gun games will certainly want to add this one to the collection. The updating of the game from the last installment is mostly minimal, but all of the things that made House Of The Dead II fun are present and accounted for in this release.
Casual gamers will most likely be put off by the short amount of playtime required to beat the game—making this a prime candidate for renting before buying.
Deaf and Hard of Hearing gamers won't be missing much—the dialogue is spoken, but can be read through subtitles that faithfully recreate what's being said onscreen. Unfortunately, you'll be missing out on some really cheesy voice acting.
