A modder named DryxioGTA has created a mod for the Grand Theft Auto series that allows players to travel between Liberty City, Vice City, and San Andreas using portals. The mod enables instantaneous travel between the three worlds while maintaining distinct saves, missions, and settings for each game. Players can interact between the cities, such as shooting through a portal, which triggers responses from civilians in the current world. A video showcasing the mod was shared on YouTube, demonstrating its functionality. Grand Theft Auto 6 is set to be released in November.
