Half-Life 2 just got a small update, mostly to fix a long-running music bug. But hiding in the patch notes is an apology of sorts, a nod to that most tenacious of bunnyhopper: the Half-Life 2 speedrunner. It seems the recent 20th anniversary update for the classic first-person shooter messed with some beginner speedrun strategies by introducing an invisible wall to a big sewer pipe. Valve have now corrected that, removing the offending blocker and restoring order to the universe. Well, almost.
