While Bawls is the prominent beverage of the Texas wasteland in the game, and a product placement advertising deal with the real Bawl energy drink, merchandise such as posters and refrigerators are dedicated to Nuka-Cola.

Fallout: Brotherhood of Steel is "roughly" placed between fallout and fallout 2.
Although not directly mentioned in the fallout timeline, it has nods to the original fallout with the original Vault Dweller, along with Rhombus, a head paladin for the Lost Hills chapter of the Brotherhood of Steel, and aspects of the super mutant uprising.
