Valve has always been good to their customers (nevermind Half Life 3) and they are rewarding their fans by giving them something from Portal 2 for free. No unfortunately it won’t be the game itself and it also won’t be anything tangible but you will be able to remember all of those great times while you were testing in those chambers.
That is because it is the entire soundtrack for Portal 2 for free. There are 22 songs from the game on this Volume 1 of Songs to Test By as well as six different ringtones that you can use if you have an Android or iPhone phone. You can pick up the soundtrack and the ringtones here. Even if you aren’t a fan of Portal 2, at least you can pick up some extra music for the price of bandwidth.
