Portal for Free!

Fearmyblink

The original and ever popular Portal, by Valve, is free on Steam till tomorrow (i believe). If you don't have it now is your chance!
I never played the original so i decided why not, it's free.

+1, You have to go to the Portal Steam Store page and activate it.

If you have never played Portal, this is your chance. Do it. I highly recommend it.
