DS shooters?

Hey, I was wondering if there are any on-rails or lightgun (without the lightgun of course) shooters on Ds other than Point Blank?

There's a house of the dead style game for the DS but I'm not too sure how good that is. I heard that COD4 and WaW for the DS were pretty good.msuspartan11

Is Metroid in this genre? Because I've heard that it's pretty good for the DS (looking for it at local Gamestop)

Moon is a pretty good game, though it isn't a hardcore shooter, more like a puzzle game

A surprisingly good shooter to look into is Bionicle Heroes on DS. I know the console versions were bad, but the DS version is surprisingly good and fun, with great graphics and fun gameplay. Definitley worth looking into.
