I have never played the original typing of the dead - weird twist on the arcade zombie shooter genre where FBI agents armed with keyboards hooked up to Dreamcast backpacks hunt zombies and other monsters by typing up words instead of aiming and shooting. There are no keyboards in this game, but it's still the same concept.
Much of the comments I could have about this game would apply to the original House of The Dead: Overkill. The words are pretty funny and there's going to be a multiplayer mode in the future, probably. There's very little replay value if you don't care about score and collectibles, which is kind of a shame, but oh well.
