I've thrown more than a couple dollars into Ghost Squad at my local arcade. It's pretty fun. There's a broad selection of weapons which you can choose from the start to suit your playstyle (Such as the high-calibre pistol which can shoot through walls or the shotgun which easily hits enemies... and innocents) and branching mission paths.
I enjoyed it much more than Time Crisis 4, which is a rail shooter that desperately wants to be an FPS. It just doesn't work.
