The Sniper wears the Razorback shield on his back, which provides him ample electrified protection from backstabbing spies. The battery-powered item is good for one use, but wearing it is said to "slow you down a little." nope "Any poor sap dumb enough to backstab you while you're sporting one is getting a surprise to the tune of 10,000 volts," writes Valve. "Plus, if they want to stab you again, they'll have to wait until their knife cools down. Which is lucky for you, since the Razorback collapses into a million finely crafted pieces after a single stab."
The Sniper update, which also includes the head-slot items, Payload Race mode, new arena maps and more, will be out within days.
