  But the version that plays with the original game.

For your gameplay, I strongly recommend that you be very careful where you place your portals because it will show you this kind of error:

Since you get the "Portal Gun" I advise you to be very careful not to skip the important scenarios and not to forget the main NPCs who follow you like for example Alyx Vance.

You can play mods from Half-Life 2! (keeping the same functionality).
