The Trojan Pig (2020)

From the introduction: Uncovered by the harsh desert winds, a giant porcine form of gold emerges from its silica slumber. As the wind whips stinging sand into your eyes, you know it’s the only shade you have seen for miles. Whilst searching for the Pyramid of Dimhotep the Stupid [or chasing another desert legend], the PCs stumble upon the giant automated golden pig constructed millennia ago. Created as an elaborate ruse, the golden pig is an automaton intended to lure an enemy king into allowing a ‘gift from the gods’—in the form of a revered animal—into their city. Little would they know that it was controlled from inside by an elite unit of fighting men, who would escape from its confines once inside the city, and slay its king. The golden pig never got that far.
