Overheat Engine
Your ships can boost their speed for a short period of time to escape torpedo fire, but at the risk of overheating their engines. After this burst of speed the ship will only be able to move slowly for a time whilst its engines cool. Remember that there is a risk of blowing up your engines when powering them so hard - so the more this ability is used, the greater the danger to the ship in question. The cooling down period between activations limits the ability's exploitability.
