Spy info
The spy is by far the most dynamic character in TF2. Using his disguise
kit he can assume the appearance of any class on either team. Once
disguised you take the screen name of someone on the opposing team and you
can even fool enemy medics into healing you. As good as it is to be able
play dress-up; once you attack you shed your disguise making it obvious to
everyone who you really are. If you really hunger for stealth the spy has
the ability to become completely invisible for short periods making it
easy to slip past the enemy lines. If that’s still not enough, you can
use your electro-sapper to destroy any sentry, dispenser or teleport. The
best strategy for the spy is to blend into the crowd, and once you and
your target are alone, walk up behind them and stab them in the back.
