Impenetrable Defense: Successfully defend Dustbowl without giving up a capture.

This achievement might be hard to get unless you have a team full of really good players working together. Dustbowl is a very hard map to defend with people who don't know what they're doing or with a team that has a really solid offense.

I suggest getting a group of good friends together to coordinate as much of your teams activity as possible. If this isn't possible then you'll just have to play a lot of Dustbowl until you get this. I would suggest going to a 24/7 Dustbowl server.

Impossible Defense:Successfully defend Gravel Pit without giving up a capture.

Gravelpit is one of my favorite maps. I love Scout and Spy and they dominate on this map for defense. While red almost always defends B and lets blu have A this isn't going to be helpful to this achievement. The easiest way to get this achievement is to stack red with players who work well together.

Putting too much effort into defending A you'll easily lose B. B is one of the most commonly defended points because you can build on the roof and the attacking team can also get on the roof. Having the upper level of the map really helps to ambush unsuspecting players below. If you have good defense on both sites you should be able to hold this down just fine.

Head of the Class:Play a complete round with every class.

If you're like me you want to try out every class. Just make sure you play a full round (no changing at re-spawns) with each one.

Flamethrower:Set five enemies on fire in 30 seconds.

Flamethrower is a very fun achievement. I suggest waiting to go for this one until you try for your Pyro achievements. The easiest way to do this is wait around a corner for people to come by.

Either that or go suicidal and charge the other team and try to spray your flame back and forth. You don't have to kill them you just have to set them on fire.
