Heat

Heat damage is a special type of harm that doesn’t count as damage and ignores Armor, although it can be affected by Resistance. It represents damage to a mech's internal systems and reactor. It's most often inflicted by electronic warfare, but is often generated by a mech’s own systems. A mech that takes Heat marks it on their sheet. When it reaches its Heat Cap, any additional Heat causes it to overheat.

If a character without a Heat Cap (such as biological characters and drones) would take Heat, they instead take an equivalent amount of energy Damage.
