How to Turn the Top of a Tank in "GTA: Vice City" on the PC Versionby Kevin Bramer ; Updated September 22, 2017
In "Grand Theft Auto: Vice City" for the PC, both criminals and police try to kill you if you get on their bad sides, and eventually the police will send tanks out to try and take you down. Getting a Rhino tank of your own in the game is difficult (although there is a cheat code), but controlling the turret of the tank can be easily done by using two buttons.
Enter a Rhino tank. You can enter the cheat code "PANZER" during gameplay to spawn a tank at your location, or you can attain a wanted level of six stars and steal one of the tanks that tries to kill you. It's also possible to steal a tank from the military base on the northern end of the first island.
Press "4" on the number pad to rotate the turret of the tank to the left.
Press "5" on the number pad to rotate the turret of the tank to the right.
