More Character Dialog in TF2

In addition to learning the maps, there are a few other things to know:

• Sentry guns beep 1-3 times each time they change directions (so about every 3 seconds). Once for mini/level 1, twice for level 2, thrice for level 3. Generally, if you can hear a sentry's beep, you'll be in its range when you round a corner.
• As a Spy, you'll get a LOT of cheap deaths. Sadly, this is because of the Spy's shortcomings in order to combat the instant-kill backstab.
  • The Spy's Dead Ringer takes some getting used to, but in certain situations, using it (preferably while disguised as a teammate so they don't know you're a Spy) can get past a defensive line. Beware that the Dead Ringer makes a louder than usual decloak sound. The Dead Ringer is a "perfect" cloak for the first 6.5 seconds, so enemies who touch you won't make you appear as a team-color outline. However, they still can't move through you.
  • The Cloak and Dagger gives you some latitude by not decloaking when you don't want to, but it also has a very short cloak time.

Having said all this, you're still going to die a lot in Team Fortress 2. It's the nature of the game! The lower-HP classes in particular are specialized in some way, but lower HP is the drawback.

While it is still in the experimental stages and only available in source code form (java), DemoReader by Asher Baker can decode and playback the voice chat audio from demos.
