push
You may choose to Push your Mech after you roll the die. This allows you to re-roll the die, but you must accept the second result. Your Mech then increases its Heat by 2 and must make a Heat Check. If you Push 'for free' you may re-roll the die without adding Heat or making a Heat Check. Pilots cannot Push rolls and roll the die once for all actions, unless otherwise noted.
