The '''CULLZONE.DAT''' file consists of seven distinct sections. Many of the zones closely mimic the <code>[[cull.ipl]]</code> file, which does not seem to be used by the game. Ignoring rounding errors, all but one section 4 zone matches all zones with nonzero flags in the <code>cull.ipl</code> file. The only zone that differs is at the Shoreside Vale subway station.

The subject of this article is not fully documented yet. You can help by researching information about it and expanding this article.

The cullzone.dat is a binary file containing zoning information in GTA III and Vice City. The file is located in the \data folder of the game's directory.

GTA III

A map of all cull zones in Section 2
A map of all cull zones in Section 4

The CULLZONE.DAT file consists of seven distinct sections. Many of the zones closely mimic the cull.ipl file, which does not seem to be used by the game. Ignoring rounding errors, all but one section 4 zone matches all zones with nonzero flags in the cull.ipl file. The only zone that differs is at the Shoreside Vale subway station.

Flag Binary Description
1 0000 0001 Both on foot using classic controls and in car, when you are in the zone in third person camera modes, the camera is stuck to a close in view. Once you leave the zone, the camera returns to its former distance. If the camera is already in cinematic or GTA 2 camera mode when you enter the zone, nothing changes. The camera mode can be changed to first person, but then afterwards changing camera modes remains stuck in third person. Once you leave the zone, it will automatically switch to cinematic mode.
2 0000 0010 When on foot, the camera is stuck in place as it remotely follows the player. The position where the camera is stuck seems to depend on the zone geometry and point of entry. The player is best controlled when in classic controls; the zone was not designed for standard controls. If you are in GTA 2 camera mode, it will leave that mode until you leave the zone. The flag has no effect on cars.
4 0000 0100 When in a vehicle, GTA 2 camera mode is disabled and becomes first person. When on foot, GTA 2 camera mode is just disabled. Once you leave the zone, the camera returns to normal.
8 0000 1000 Rubbish is limited on the ground and there are no raindrops when it is raining. The weather can still be rainy though, like dark skies, reflective ground, etc.
16 0001 0000 Cops in vehicles will ignore you but you can still attain wanted level as usual. They will not chase you or use their siren. Police cars still spawn as usual when you are wanted. Cops on foot seem to be stuck in a spot when spawned but sometimes they can move to a limited extent. They will still shoot at you like normal. Once you leave the zone, they will resume chasing you down.
32 0010 0000
64 0100 0000 When traveling under z = -4.0, by default all level transitions are disabled. Entering the zone resumes any level transitions. This flag is redundant on zones above that height as level transitions are also resumed when you travel above that height.
128 1000 0000 An interior system like Vice City and onwards was implemented for GTA III's subway system and tunnels. They are by default invisible. When you are in the zone, they will become visible.

Vice City

In addition to Cullzone.dat, Vice City has a file called Cullzoneempty.dat. Both of these files are not used by the game at all. The game uses the cull.ipl file instead.
