portal additional maps

[okeee]

im playing this game on win xp.
for the game "portal" have they any official additional portal maps? i dont mean the "bonus maps" where you just have to play the same levels but in harder modes. but new, extra maps?

No, I don't think there are any 'official' extra maps.
There is a lot of community made content to sift through on various forums and mod/map websites like filefront.
You could check out something like the moddb page for portal to find some good maps and map series.

Valve announced that they are developing some sort of creation kit for custom Portal 2 maps this year. There are custom maps that are made on Hammer for Portal 2 though, I think the new one has a lot more of that kind of stuff than the first.
