No, Benitsubasa is actually right. These aren't hacks, these are game functions already implemented using the Steam console, what we are doing is forcing a new method of input.
You can do any of these commands without the use of the programs, save for the numbers at the end, as he pointed out. This tool just facilitates that. You're not technically doing any hacking, you're merely modifying the parameters of the game using pre-existing functions, AKA the cvar/cmd commands o_o
Which I guess is "hacking" since you are modifying the game in a way it wasn't intended to, but meh.
Do note that this is a Source game. He's right on most accounts, we should be focusing more on decrypting the .hfs files, decrypting the packets (somehow), and creating more clients like the ones they have at artificial aiming etc, but those are pretty hard to code.
