Catching Elephant is a theme by Andy Taylor
While Africa was hit by many nukes in some places (especially in North Africa), it got off comparatively nuke free. Things still went badly in the immediate aftermath, especially near the heavy-nuke zones, but as a whole, central Africa is probably the most populous and wealthiest region in the Fallout-verse, and they have a lot of tech (running on Fallout-logic, of course) that is very reminiscent of steampunk in aesthetic, though they also have a fair share of pre-war tech and pre-war design plans at the core.
All of this and also intelligent two headed elephants. Because.
