Molotov Cocktails are a thrown incendiary weapon that has appeared in Grand Theft Auto games since the earliest entries and are due to appear in Grand Theft Auto VI. True to their real-world namesake, they are depicted as home-made devices, a rag-stuffed bottle of flammable liquid that ignites on impact and sets a localized area ablaze. Across prior games they have been sold through outlets like Ammu-Nation and various street dealers, though no pricing or availability has been confirmed for Grand Theft Auto VI.
