CONTROLS:

[keypress G] = Recruits nearest ped.
[Group CTRL back] = Releases them from your gang and they become a regular ped.

Recruited ped is given an Uzi and will attack and do drive-bys on other gangs (other than Grove) and cops. Drug dealers are not recruitable, though.

I commented out setting the recruited ped immune to everything if the subtitles are on. You can uncomment that if you want that function.
