Add a new bullet to the list of actions detailed in the rule entitled Turn-based Actions, with the following text:

Follow-through. If a Gladiator has been shoved since the last Turn Boundary, and has not taken a Main Action since the shove took place, then he may Follow Through as his next Main Action. When a Gladiator Follows Through, he may take a single Step or Shove at a cost 1AP cheaper than it would usually be, provided that it continues in the same direction of travel as the initial shove.
