Hi guys, i buy the game and i have Orange box( with HL²+ episode 1+ episode 2 + portal + tf2 + hl² lost coast + hl2 death math )
So i was wondering if i need to install every thing to have the best experience in the game ? and wondering if i need to install SDK source too to have the best experience in the game ?
NB 1: By saying experience i mean to play with no crash and with all the items i can get. Cause i install gmod but when i played i had some weapon of th2 ( the new one who comes with the up dates ) was purple and black. I could see their real color.
NB 2: Sorry for bad english, i am french and french people are knowed to have a bad english.
NB3 : Ty for your help guys
