Nah, I didn't, I honestly still haven't finished playing through Quake 2's SP, although I've been working on it. I got it with the special edition of Quake 4, along with the expansions, but forgot about it until a couple weeks ago. I'm just irritated at the last couple levels, and I'm having more fun playing Granado Espada, and raping people multiplayer than shooting really ugly strogg, rofl.
I never did play AHL, but I looked into it a couple years ago. The only similar thing I've played is The Specialists, which kicks serious ass. I freaking love that mod :V
