The Sniper update reveals itself to be the Spy update

The latest update to the Team Fortress 2 blog details the Spy's new weapons. Apparently, Valve used the Sniper update to stealthily infiltrate the enemy base. Revealed today are weapons the Spy can use to counter act the Sniper's new advancements. Its good to know that Valve remains dedicated to keeping the game balanced while all of these updates are rolled out. I just wish there was a slightly newer game mode (instead of just a redesigned Payload mode).

The spy can now trick his enemies into thinking they've already killed him while he sneaks behind them, invisible, to stab them in the back. The spy also has a new invisibility cloak that will keep him in hiding for an indefinite amount of time so long as he is standing still. These updates seem to introduce a slew of new tactics to the games expert spy players will have to master in order to be successful behind enemy lines. I'm not much of a spy player myself....

To date I've only played 4.6 hours with the spy class (out of 70 hours total since the game was released back in 2007). Jeez, I'm such a casual....
