I have 3 major questions for map creating for Team fortress 2 Classic for my brother. And if Garden Freeman and Agameofscones could help me that would be fantastic. 1. What version of Hammer would one need to use in order for the map to run on TF2C and for it not to crash the game. 2. How to get exported properly to run. 3. If people would be willing to give feed back on the maps if he ever makes it. Thank you.
