Valve, in true creative fashion, dropped the bomb that the upcoming Sniper pack soon to be released is instead a Spy pack. Turns out the Sniper really was a Spy. With the news, we get word of two new unlockables, the Dead Ringer and the Cloak and Dagger.
With the Dead Ringer equipped, when you take a non-lethal shot, you immediately cloak for up to 8 seconds and leave a corpse behind. The amount of confusion and insanity this thing can leave is going to be nuts. Now, even when you identify and shoot at a Spy, you can't be so sure you actually killed him, leaving you even more paranoid and confused. On a server with friendly fire on, this is going to be absolute mayhem.
The Cloak and Dagger is a new cloaking device that will allow you to be cloaked indefinitely provided you aren't moving. In fact, that's the only way the device will recharge, is to stand still. It's a trade-off, but a fair one - it's a better cloaking device, but if you want it to recharge, you have to effectively take yourself out of the game for a few seconds.
And not only did Valve see fit to surprise-release a pack for my favorite class, but they also put out a new "Meet The" video, "Meet the Spy". It's hilarious, fitting, and embedded just below this sentence.
If I didn't know any better, I'd say Valve was trying to get into my pants. I can't wait for the Spy update.
