You will be booted from rooms if you blatantly hack. I dont support hackers, but first you need an injector, so go search for Portal. And then when you get it, get a hack from the hacks section, and extract it so that you get a dll. Put the dll in a folder and then open portal. And then when it opens, press on the top left corner and a menu will drop, then press preference and direct it into the folder you have the dll in and press ok. Then in the game use insert key to use menus and arrow keys to activate hacks.
