I apologize for all teh questions I've been asking lately, but i've tried to look for these for the past few days and have come up empty. Google fails me.

I'm just goign to list them, and answer or ignore them if you want.

-What steam tools exactly do I have to DL to make maps? Theres 'Source SDK' 'Source SDK Dedicated Server' 'Source SDK Base'. Do I need all of them or just a few of them to make maps?

-Do I have to download and install Zombie Mod to be able to test them properly once the map is made? Same question if I'm just downloading maps and are testing them myself.

-Parachutes. Are they a downloaded mod or is there a console comand to activate it?

thank you for your time.
