The Burton Equation focuses on the trials of an involuntarily time travelling detective, Zachary Burton. He is whisked through time by an unknown agent to counteract attempts through human history by the Combine to conquer humanity in the 20s, 40s, 80s, and HL2/2010s. Time is an equation, and you're here to solve it.
