The guides on youtube teaching how to "play portal in hl2" are not updated...

Altough, i have a solution: What you do is:

What you need:

Portal game.

HL2 maps (Can be found inside the game files).


Step one: Locate both HL2 and PORTAL "advance chambers" folders in your steam directory.

Step two: Copy and paste the maps from HL2 into the portal folder with "advance chambers".


Step tree: launch portal, and start the advence chamber called "intro"; if you are stuck go into your console and type: Changelevel "D1_trainstation_01".

Hmm, never tried this, thanks for the tips!

Wow... Sure makes you wish you had Portal... Lol
