1. Drug trafficking: There are sometimes some small blue dots in various small alleys in the game, and these blue dots are drug trafficking points. After trading with them once, the little blue dot will become a box and be recorded on the map.

There are 81 drug trafficking locations in the game. Here is the map: /1911/121347662159.html

Arms: you can only buy them, but you can't sell them. In the menu, item $ is purchased first.

2. This game needs to change the boot mode to SONY 9661 in standby mode. Just press SELECT in the system menu and there is a UMD MODE.

3. The tank is in the rightmost map airport (there is an obvious rectangle on the map at the upper right). Generally, the tank will enter a small game. If you want to drive the tank around the city, you need to hit the tank with a car next to it to move a little, and that's all.

4. There is no military base in the game, but only a few small islands that can go down to the sea.
