There are two files in my save.
One - where all missions have been completed and where one final mission has not been completed. All schools graduated with gold medals. Karl has pumped all shooting skills. All the territories of the gangs have been captured. Also, upon death or arrest, you do not lose your weapon. Karl has $ 999,999,999 in his account.
The second is the same, but everything has already done 100%.
