I am so glad that this mod was released again. It was quite entertaining to play it again. Furthermore, the new maps are amazing and look very similar to the maps we saw in early screenshots and gameplay videos of Portal.
Thank you! :D

I want the actual betas but no one will release them which i dont understand Valve gave them out to some people but they wont share them. Why did Valve specifically chose them?
