Must have downloads?

Hey, i just bought gmod from steam and want to know what downloads i need to have to play on most servers. (like spacebuild, and common things)

Thanks!

PHX and wire.(both SVN)

and also consider buying cs:s hl2 ep1 and ep2. these are games mainly used in gmod.

FapHack

FapHack is buggy.

Then tell me how so as I can fix it.
