Hiss!), but then things started getting interesting. I caught a balloon that had drifted from London to Texas to Arizona, picking up new notes along the way.

With Halloween fast approaching, it's a great time to get in some practice defending your territory against zombies. In Graveyard Shift, you take aim at zombies and other creepy-crawlies, blasting them into splatters of cartoony green guts. It's a casual first-person shooter, and it's very easy to get the hang of - use the mouse to aim, click to fire. Graveyard Shift has at least 15 levels, and it might even have some secret stages I haven't unlocked yet.
They key to getting good at Graveyard Shift is learning to use ...
