Free Portal

So the guys at Valve have announced they are giving away free copies of Portal until the 20th of September. So if you don't have it now I suggest you go download it now. This is to do with their 'Learn With Portals' initiative. Along with this offer of yet another free game, they recently had a bunch of 7th graders on a school field trip at Valve HQ, letting them play about with 'Hammer', Valve's level design program. I am very jealous of these kids, not one field trip I went to at school was anything remotely as cool as this. Watching the video makes me want to break out the old Hammer tool and get back into using it again.
