Works great for first 5 classes but certain perks/attachments won't work for the later classes (6-15). I'm using Win7 64-Bit. Happens on both my laptop and desktop. You might want to re-label the "Extra Weapon Proficiency" option with "Secondary Weapon Proficiency" to alleviate confusion. =P Great, quick release though. Maybe give options for tweaking the attachments to your secondary weapon in the next release?
can they find out if your using damage proficency on other guns besides shotguns and get you banned ?
yeah. anything beyond class 5, i cant seem to edit.
You can achieve exactly the same thing with the SearX v6.0. Download it, go to barracks, start it up and click "class customization".
Then choose a class, and edit the class to your likings, and as secondary weapon choose the proficiency and choose whatever you like,
such as : UAV ( Gives you unlimitted UAV when you switch to your secondary weapon ), ballistic vest, perks, etc...
Voila ! Exactly the same effect as this secondary weapon effect + much more untill the secondary weapon hack gets updated.
Make sure to close the hack before leaving the barracks for less chance of it getting detected.
Is the UAV giving the other team UAV too?
