Backstabbing spies aren't going to be too fond of the most recent addition to the Sniper's load out. The Team Fortress 2 class has a new friend in the new unlockable "Razorback."
That is to say the Sniper's new shield has got his back. Valve released details on the battery-powered tribal shield today, which looks to prevent instant-kill backstabbing attempts from Team Fortress 2's sneakiest of classes. If a Spy does attempt to backstab a Sniper wearing the Razorback, he'll be greeted with 10,000 volts of surprise.
We're still a little hazy on some of the particulars, especially the single-use nature of the shield, but we're following up with Valve to see if we can sort out our questions.
