TF2 Thread, now featuring HALLOWEEN!

Sniper is quite straight ahead.

Engie, just know where to place your buildings.

Spy, it's all about blending in. Never look your victims in the eye, or act suspiciously.

I'd like to add to these.

Sniper: Go for head shots, and nothing else. It's a lot harder than it sounds too! Unlike Halo, or whatever other FPS is popular now days, every single enemy has a different movement speed that you'll have to adjust to. Sometimes there are people with items that will give them a quick surge of speed, such as the Charge 'n Targe, and you will have to adjust accordingly in order to get a head shot, otherwise the enemy will break through and wreak havoc on your allies. Any good sniper should also be sure to learn each enemy player's movement patterns and habits, and be sure to spy check regularly. Most veteran snipers are also able to get their cross-hairs near or on the enemy player's head before zooming in, this skill is indispensable as you have to be able to quickly shoot an enemy with or without charging up so that other snipers won't have an opening to kill you.

Engineer: Trust no one, as spies will stop at nothing to sap your buildings and back stab you while your sentry is inactive. If anyone even begins getting near one of your buildings, give him a few rounds from your shotgun or pistol. You should also have your options set so that you will see the damage you deal as well as hear a dinging noise whenever you hit an enemy, this will allow you to know who is a friend and who is a spy trying to sap your buildings. Make sure you keep your sentry gun at peak condition as often as possible, and try to find narrow doors and hallways that you can use your buildings to block off. Your allies can walk through your buildings, while enemies have to break them down to pass, use this to your advantage. Find places to set up teleporters that are out of the way or hard to reach so that spies won't sap them as often, remember that any damage done to one teleporter is also done to the other. If a spy does get through and starts sapping your buildings, then ignore the buildings and kill the spy ASAP. If you leave the spy alone, then he will come back and continue sapping your buildings or backstab you while your distracted. If you're using the Wrangler, make sure not to shoot yourself because the sentry can hurt you too; however, you can use this to your advantage as a method of getting to high ledges called "Sentry Jumping." Sentry Jumping is incredibly useful for placing buildings in places that can easily hit enemies all around the map or provide great spots for teleporters so that your team can safely travel into enemy territory, but be sure to bring enough metal with you because you won't have a dispenser when you get onto the ledge you want to reach.

Spy: First and foremost, decide on what kind of spy you want to be! You have to think carefully about your equipment setup, as it drastically affects how you're going to play as a spy. Are you going to be a spy that utilizes the default Invis Watch to move into enemy territory quickly and without stopping, or the Cloak and Dagger so that you can camp in populated areas and ambush enemies, or perhaps you want to be more offensive as a spy and use the Dead Ringer so that you can surprise enemies who think they've killed you? Well alright, now that you've made your choice as to what type of spy you want to be, you have to learn where to hide when needed, as well as some of the basic patterns your enemies follow. You'll also want to learn ways of backstabbing enemies who don't have their backs turned to you. Yes, it can be done! The hitboxes on the enemies' backs can be fickle little bastards, and depending on the situation you can get a successful backstab from the side or even the front of an enemy (frontal backstabs are known as "Face Stabs"). You must also know when to retreat and how to navigate the map backwards. If you can navigate your way back to your base or to a health pack while running backwards away from an enemy, you'll have many more opportunities to shoot him with your revolver and possibly recloak so that you can hide and get him again when he gives up on looking for you. A helpful tip to all beginner spies is BEWARE OF PYROS! Pyros can ignite you, which renders your cloak useless as well as causes damage over time, additionally their air blasts can prevent you from reaching health packs. Pyros also excel at spy checking, as their flame throwers have a decent range, fire continuously and will expose you if just one of the particles touches you. If you find a Medic + *something* pair, go after the medic first and try to get a backstab, if the other guy remains oblivious to your presence, then you may try and backstab him as well. When you see a sniper using a Razorback, do not attempt a backstab, use your revolver (preferably the Ambassador for headshot crits)! You must NEVER assume your disguise will keep you safe. Yes, the disguise kit is incredibly useful, but never assume that the enemy trusts you because of your disguise, in fact most veteran players will shoot teammates to make sure they aren't spies. While cloaked or disguised, avoid narrow or confined spaces, as enemies cannot walk through you like they can with their allies; thus, you will be exposed if you bump into an enemy or enemy building. One last tip is to use enemy buildings to your advantage while your disguised. If you see and enemy dispenser, try to get some health and ammo out of it if you need it, and when you find enemy teleporters it's a good idea to take them since they usually lead you to where the engineer has set up all of his buildings. Once you make use of the enemy buildings, sap them and see if you can get a backstab on the engineer. If the engineer is smart and tries to kill you before tending to his buildings, then run and come back later.
