Portal: The Forgotten Alternate Reality Game - Inside A Mind

  • Published on: 17 May 2019
  • In 2010, the creators of the game Portal put together an Alternate Reality Game with almost no budget in hopes to help promote the second game in the franchise, Portal 2. So many easter eggs were found throughout the game such as memos from CEO of Aperture Science Cave Johnson, a GLaDOS and Doug Rattman log in account, and even hints towards what we would be seeing in the new upcoming game, Portal 2.

    I like how you can translate the Lemon Rant (In a metaphoric way) so it like taking the red pill in Matrix. And this is smh fitting so well in this video: The Gamers and interested who tried to decrypt the Alternate Reality Game

    Portal might be my favorite game series. I really hope they someday make it a trilogy.

    I totally remember this! Being a ham radio guy, I immediately recognized the slow scan tv or SSTV sounds. I was decoding the images myself at home. That whole augmented reality game sucked me in and I couldn't wait for portal two after we all figured it out.
