Gauge Games in a Unified Field Theory

Gauge symmetry is enforced in the Maxwell action written with quaternions by a subtraction. The action is rewritten using hypercomplex multiplication rules and the same method to ensure gauge symmetry. The hypercomplex field equations contain Newton's law of gravity, a time dependent term, and an Ampere-like equation. Gauge symmetry for light and gravity can be broken by not doing the subtraction. Yet Maxwell and the hypercomplex field strengths can be combined to form a gauge-invariant unified action. Neither the Higgs mechanism or general relativity are needed.
