Viewers in the past, sorry for late response. I haven't been paying attention to my Youtube much.
Or in other word, my first HD movie :D
How to play "Hunter Training" on Left 4 Dead 2
Instruction 1. Download the map here http://l4dmapdb.com/local--files/addo... (not my file, thanks to the person who uploaded this!) 2. Download Winrar if you haven't. 3. When the download completes, you have to drag the hunter_training.vpk file to your addons folder. You can not double click it anymore! 4. Launch up Left 4 Dead 2 and type in, "map hunter_training versus" (without the quotes) in console. 4a. To enable console, go into options, multiplayer options, and it should be there. Enable it. 5. If you have question, just ask in comment, I will respond to you ASAP.
