Overheating in BTA has been completely overhauled and no longer deals structural damage. Instead, you can be forced to shutdown, experience ammo explosions, pilot injuries, or critical hits, and experience significant movement and attacking penalties. These changes are tied to the Classic BattleTech (CBT) extended heat scale, which normally ranges from 0 to 50 heat. The HBS game expanded heat values on a 3:1 basis, so this implementation uses a 0 to 150 scale for heat. Multiple effects can occur at the same heat level, which can result in the unit shutting down, having an ammo explosion, and injuring the pilot all at once!

The chances below are displayed in a tooltip shown when hovering over the heat bar in the bottom left corner of the UI, just above the 'Mech paper doll. These values are dynamically updated when you target an enemy, so you can predict will occur at the end of your turn.

  • Attack Modifier is a penalty to the unit's chance to hit.
  • Movement Modifier is a penalty to the unit's base Walking Speed, which also reduces its running speed.
  • Shutdown Chance is the threshold a percentile check (d100) must equal or exceed, or the Mech will be forced into a Shutdown.
  • Ammo Explosion Chance is the threshold a percentile check (d100) must equal or exceed, or the most damaging ammo box remaining will explode and inflict internal damage.
  • Pilot Injury Chance is the threshold a percentile check (d100) must equal or exceed, or the Pilot will suffer one point of damage.
  • System Failure Chance is the threshold a percentile check (d100) must equal or exceed, or one randomly selected internal component will be destroyed.
