In the latest update, Valve added this board. And it's very mysterious.
actually i'm wrong the board is on 2fort, hydro, badwater, lakeside, lumberyard, decoy, and doomsday too
another few things about tf2:
-valve still hasn't completed the training mode and making it mandatory for new players
-they hyped up red and blu teaming up to fight gray mann and his gray robots, but they pulled the ol' switcheroo and made it red vs. blu. so really nothing's changed
But the whole point of HL2's maps were to give you the illusion of free choice by making the maps look huge with tons of different ways to get around, but really you're just stuck on a linear path through the entirety of the game.
Making hl3 open world would contradict what hl1 and hl2 set up.
opposing force's original soundtrack didn't work on the steam version so they just shoved in half-life's soundtrack. the pipeline update changed it to the original soundtreack
not sure if blue shift had an original soundtrack
So what does that have to do with anything? I'm sure if they wanted to tell more about him they'd include it on the update page, but for right now he's just a generic skeleton with no backstory.
