A Molotov Cocktail is a thrown weapon in Days Gone.
Molotov's can be crafted by Deacon with components found throughout the world, but due to them being easy to make and carry would also be found in camps or on other survivors. Ingredients would include alcohol or a similar flammable substance and a rag or fuse of some kind.
Molotov Cocktails are very versatile, allowing them to be used in a multitude of ways. Most uses would involve clearing out Freaker Nests or eliminating groups of wandering Freakers. They can also be used to suppress other Survivors or eliminate them altogether. They can also help with eliminating a Horde, something that will require a lot of resources to deal with. Molotov's can also be a good way of keeping enemies back, allowing for a much needed escape.
