The only way to get Portal for free is by illegally pirating it via certain sites. (Which I think that is a really, really, REALLY bad idea...)
However, you can get a demo called Portal: The First Slice on Steam...
Once in a while, Valve will have portal be free for a while.
You can buy Portal from Steam. Portal was free on many occasions but it is currently a paid product.
Ok Portal still alive is bonus levels and there is a game called portal 2 already
It is free on Steam until the 20th of September. Just go to the Steam store and search for Portal. It says it costs money but you can install it without paying. Enjoy it, it's a very good game.
The population of Shockwave - game portal - is 100.
Portal is the original game in the series. Portal: Still Alive is just extra levels added to the game.

...ummm...Portal?
Will that heartbroken
No. It will cost money. Portal costs money. It was only free for a limited time.
Steam. It's free to make an account and you can buy and download games including game demos and full games. They sometimes have special offers! I got portal for free with steam when there was a portal special. It's wifi so if you want to play multiplayer wifi with a game you can ask a friend to play it with you... if they have the game.
