On Garry's Mod.org is a planet development kit for Spacebuild.
But I have a question: where does it go?

Where do you extract it?

Okay ill find something else then, cause my computer has like 5 gig left : (
I really want to get it though.

Think of it this way:
GlaDios has the mind of a child. She is curious, impulsive, and when she does something wrong, she tends to try to lie and cover it up. Not only that, but remember when she comments "This is the only thing between us and them"? Portal takes place around the same time as Half-Life, so maybe the Xen Invasion screwed around with her main core. Perhaps the workers tried to destroy her and she revolted (like in Terminator). I think that wowlord is half-way right: GlaDios isn't ENTIRLY innocent: she just didn't know the reprecussions of her actions until after she released the Neurotoxins.

I read it. And then I read another article about it. And another. Seems everyone agrees with you.

But would he really need a bomb?
If he isn't Half-Life's version of God, he sure is close enough.
Cause, he just walked through the Black Mesa like nothing was going on.

Not in graphics, but on the PC you can get a bunch of add-ons and mods that jreally help the experience. Also, you can turn scaled leveling off in the PC verson.

How much does it cost to join now? I used to play, but I haven't for a long time.

CoD4 was the only Tom Clancy Worthy one...
Too bad he skipped it. Well, do you want to fight people, or zombies and aliens?
