Try perx injector you must have dotnerframework 3.5 or up and remember if you dont run everything as admin it wont work.
and here Step 1. Find a hack that isn't patched. This can be done by checking the latest comments, comments can usually tell you if the hack has a virus or if it is working or not.
step 2. Download the hack/.dll to your computer. You must have winrar.
step 3. Open the downloaded file and drag the .dll to your desktop.
step 4. Find a suitable injector for the hack. I suggest you find Finject or Xinject-Perx,
These can be found at ----> CrossFire Spammers, Injectors and Multi Tools - MPGH - MultiPlayer Game Hacking
Step 5. Download one of the files in the link. Open the downloaded file and drag the injector to your desktop.
Step 6: Open your injector,(if Faith injector is opened go to settings and mark inject automatically)
Step 7: Usually in the first blank. where it may not say anything beside it, or it may say "What to inject" Type in "crossfire.exe" (without the quotations)
Step 8: Next in each injector there either a browsing button or a "..." button click it.
Step 9: Type in the search bar the name of the .dll file. Once you have located it select it, then click open.
Step 10: Open crossfire, and let Your hack do the work. (DO NOT PRESS INJECT THE HACK WILL DO IT AT THE RIGHT TIME)
Step 11: Usually a box will come up saying like " Succesfully injected" and etc. Wait about 10 sec, dont click okay. If by 10 sec crossfire doesn't open then click ok.
^ this is because some hacks, don't require you to press okay and if you do press okay the hack will mess up. While some only allow crossfire to work if you press okay.
Step 12: Log in.
Step 13: enter a channel with low people, and a room with a low people.
Step 14: Enjoy owning.
Things you must have. Dotnetframework 3.5 <--- it is a must.
An .dll or hack.
If this works thank me.
