New Team Fortress 2 Sniper Update: Razorback (Day Three)

Man, these updates are not getting boring, that's for sure.  What's new today? Well, today is national Anti-Spy Day!  This new unlockable replaces the SMG (I think) and is an amazing anti-spy device.  I'm pretty sure that all you need to do is equip it in the loadout screen and you can use your other weapons normally, with the exception of your movement.
