before this achievement i had city of 170000 pop. and 12000000 of money. now i have pop of 2500 and -2000000. i did this by increasing all taxes to 29%, swiching off all police stations, cut budgeting to minimum on water electricity school transport hospital rubish...on everything, on policies tick on no pets and no smoking, raised taxes on lowhi rezidence comercial office. with this configuration i had 64% crime rate. problem with this u have to hold 50%crime rate for 5 weeks, many times my populations got wiped out before reaching 5 weeks, or on last week due to low population (<1500) crime rate decreases below 50%mark and fail. u got to balance crime rate before wipeout, keep it about 58%, what i did was some times i enabled water supply and power for very short durations. hope this helps
