HL2 PortalDuring my daily internet escapade of the day, I came across what looks like a great reason to play through HL2 again. Some modder dude figured out how to get the Portal gun into all of the HL2 levels, and he posted a Youtube video along with the blog post. This is the coolest looking game mod that I’ve seen in a while; the only downside is that you can’t just run an installer, you have to do some manual editing. In any case, take a look at it here.
