Portal Mod: Portal: Prelude
0One of the earliest and well-known Portal modifications, this one being an unofficial prequel to Portal, taking place before the activation of GLaDOS. Human employees are working around Aperture Science, and observing the test subject, Abby, as she progresses through multiple test chambers. The G-Man can also be seen in the game multiple times, but other than that one piece of dialogue, I didn't really catch him that much. The game also makes use of a few new testing elements not seen in base Portal. There's also a few familiar areas seen in the game. Near the end of the game, the party is delayed for the activation of their new central AI, but that delay seems to be indefinite because of what she did after that. And now I feel like that one song is GLaDOS's true favorite song.
