Why GTA 3 and Vice City hid a secret physics system in their trash

A former Rockstar North developer has explained why Grand Theft Auto 3 and Vice City were filled with litter. Obbe Vermeij, who worked on the games, revealed that the trash wasn’t just for show—it had its own physics system. His comments also shed light on why the feature disappeared in later titles. Vermeij introduced the litter in GTA 3 to make the city streets look messier. The system used four basic types of trash, each created from a simple rectangle with different textures. The debris didn’t just sit there—it reacted to in-game wind and moved when vehicles passed by.

*Vice City* expanded the system with a fifth type of litter. Players could only see this extra trash after completing the mission *Dildo Dodo*. However, the feature wasn’t perfect. A glitch sometimes caused the litter to clip briefly through the pavement. Vermeij later reused the same trash mechanics in *Manhunt* (2003), with help from other *GTA* developers. But when it came to *GTA: San Andreas*, the litter was removed entirely. Some team members disliked the effect, leading to its quiet disappearance from the series.

The litter in GTA 3 and Vice City was more than just decoration—it had its own interactive behaviour. Though it vanished in San Andreas, Vermeij’s system left a small but memorable mark on the early games. The feature remains a quirky detail for fans who noticed the moving trash on the streets.
