Hi! I’m frozencrazytuna! I’m completely new to speedrunning and have never ran a game before, but the community seemed so awesome that I felt tempted to give it a try. I was thinking of trying to learn Half-Life 2 but I have no idea how to begin, so to anybody that could point me in the right direction, I’d greatly appreciate it

Welcome to the forums, and good luck on the running!
