Nowhere.
Wait, let me clarify: nowhere, legally. And we don't answer questions about how to do illegal things.
Yes, first download steam, make a account, then find tf2 in steam and download it. Its free now. (TF2 takes about 3-10 gb of space.)
Download it from one the many places on the internet; Place the map inside: C:\Programfiles\Steam\Steamapps\YourName\TF2\TF2\Maps
download them from garrysmod.org
There is no way you cam change props in Prop Hunt TF2.
The only way to get TF2 is to first install steam and create a steam account. Then search in the steam store for Team Fortress. You will find it there and will be able to download and install it. but if you have just joined Steam then you cant get TF2 because they wont allow you to get any free product until you have paid over £10 I think it is on anything in there store.
no
You can download them as mods by pressing download file on the bottom right of a page. Then you have to put them in the mods / workshop folder in your tf2 folder
No downloading team fortress two does not download any virus and it is a very fun game! :)
You either buy them from the TF2 catalog or you get them in random drops. So far there haven't been any way to get them for free, aside from trading and finding them.
You go to steampowered.com download the steam app. After getting the download, open the app, click store, search team fortress 2 and then click install.
YES
Yes. TF2 is a GREAT game, and I recommend you "buy" it. TF2 is now free to Play.
