"Similar to the gameplay of the House Of The Dead series, the player must kill hordes of zombies. The difference with this game however, is that the player uses a keyboard instead of a gun, to type the correct words to kill the zombies."

I have a dedicated House of the Dead 2 cab in my game room, and I would think everyone prefers the light guns over a keyboard.
Ok, that's news to me, I had no idea keyboards were preferred over guns for shooting games. I just don't see it being popular in my area, or in the local arcades.
Then again, I haven't played this keyboard style game yet, sounds like it has its merits.
As for the actual question of this thread, they are pretty good. I have done one order through them, it came relatively quick and everything was as advertised... I had no problems, I am sure others here have delt with them as well.
