The first and second keys did not mean to activate the sandbox. (Just like turning the power on and off)
It meant using certain features of the sandbox. (Teleport, cut-scene reproduction, etc.)
Youtube and many gamers say, "What's the first key and the second key?" The reason I asked the question was that I was mistaken as I was.
But the sandbox still does not work. Does it work only in English version language?
My Sains Row 3 is a Korean version. To activate sandbox mode for more than 20 hours
I tried but failed. I was very tired.
