Top 9 TF2 classes

Engineers basically sit around and watch their machines slaughter enemies, and heal their team mates. Ocasionally, engineers hit friendly players to spycheck them, and whack his machines to repair them.

Spies have a move called backstab that kills an enemy player. Spies can also disguise as an enemy player, so sentries won't annihilate, and enemies will think you're one of them. Except for those pyros and engineer who spycheck every player.

Demos can be destructive, or be a swordsman. A demoman can set traps and blow everyone up with his raw power, and a demoknight decapitates enemies.

As a pyro, you can counter most enemies... In close range that is. You can burn enemy spies, deflect projectiles and medics, burn snipers close range, ambush and burn scouts and heavies. Unless your pyro is equiped with a flare, you are pretty much useless in long range, since I play almost exclusively in close range, the pyro is the best offensive class for me.

Heavies are basically just slower bulkier soldier, but instead of a rocket launcher you get a minigun, and you can't rocket jump.

Soldiers decimate everyone with their rocket launcher, and can go close quarters with his shotgun. He can also rocket jump, and soar through the sky.

You heal people with your medigun, and fill up your ubercharge. When an ubercharge happens you'll get power ups, like invincibility or critical hits for the player you are healing.

You run fast, do high damage, but are frail. I don't like scouts because, I am terrible as a scout, but a scout run around me in circles, and defeats me. When I run around in circles, harassing the enemy, they kill me till I'm dead.

As a sniper, all you do is headshot people for a one hit kill until a spy comes, and backstabs you. If someone comes in your camp, you're basically dead since your only good weapon is your sniper rifle.
