An introduction to the Classes in Team Fortress 2

At a glance, it is somewhat easy to see that this is not a run-of-the-mill shooter. I play it, and think it may be one of the best FPS games that exist, due to the way the many classes and weapon combinations bounce off of each other. Skilled weapon handling, strategy, and teamwork are what you need to succeed. Onto the game, There are 9 classes, all with their own vastly different pros and cons.
There are 3 types of classes, offense, defense, and support. The offense usually excel at attacking and breaking through enemy lines. Defensive classes focus on forcing the attacking players away. Wheres support are auxiliary fighters and help their teammates. These are the offensive classes. First, Scout.

 A fast, scatter-gun wielding, low heath, high power runner. He excels at lightning attacks and taking objectives. Next, Soldier;

He is a slow-moving powerhouse armed with a very powerful rocket launcher. The last Offense class is the Pyro.

He moves at an respectable speed, with a devastating close-range flamethrower and flare guns.

Next, Onto Defensive classes. First, The Demoman.
Armed with a Grenade Launcher and a stickybomb launcher, (which launches bombs that explode on command)  and shields and swords.

After that is the iconic Heavy. He is the without a doubt the slowest class in the game, but also one of the most powerful. Armed with a Powerful mini guns, the heavy is a dangerous defensive (and sometimes offensive) class.

Finally the last defensive class, the Engineer. At first all he has is a shotgun and pistol. But he is also able to construct helpful buildings with metal, which in include a extremely powerful self-acting sentry, a dispenser which refills a teammates ammo and heath, and teleporters, which can take a friendly player from one point to another.

Now onto support. The first is the always needed Medic. Armed with a medigun that can heal teammates with alarming frequency, and an alibied useless syringe gun, the medic is essential to any team.

The next support class is the pesky and outright dangerous sniper. Armed with long range sniper rifle, the sniper is a class that helps eliminate long range threats. He can be an auxiliary class up close, with SMGs, jarate, and other various weapons.

The last class is the class "No one loves. but always wants to play." The infamous Spy. He is armed with a Revolver with questionable firepower, a watch which can make him invisible, a sapper which disable and slowly destroys buildings, and a disguise kit, which changes his appearance to that of an enemy player.
