Heat is a waste by-product of firing weapons, using Jump Jets or specialized equipment like MASC or the aerospace afterburner. Heat buildup is harmless until your asset exceeds the yellow line, at which point the asset's weapons are locked out and it reveals the asset's location to all enemies that are currently using active radar. Overheating into the red-zone will trigger an AutoShutDown for ground assets, and will deal massive armor and heat sink damage to all assets.
Heat Sinks help your asset dissipate heat. The rate at which heat is dissipated depends on a few factors:
- The number of heat sinks your asset has. More heat sinks means more dissipation per second.
- The current map. Some maps may modify how well your heat sinks function, either improving or reducing their abilities.
- Your total heat. When your total heat is higher, it will dissipate faster.
- Your current movement. Remaining stationary enables for faster cooling.
- Moving into deep water will dramatically improve heat sink efficiency.
- Whether your asset is powered down or online, powered down assets cool faster.
- Your heat sink health. Damaged heat sinks cool more slowly.
Overheating too often can damage your heat sinks, rendering them ineffective.
You can Flush Coolant to rapidly exchange heat with your surroundings by pressing the [ C ] key. However, your asset carries a limited amount of coolant, so use it wisely. Be aware that when in lava, like on TC_Inferno, using coolant will still exchange heat, but will cause your asset to increase in temperature instead of cool.
Coolant is refilled whenever you repair your asset, and damaged heat sinks will also be repaired.
- Every ground asset has automatic overheat protection also known as 'AutoShutDown' - when it kicks in, your vehicle will shut down to dissipate heat more rapidly and to prevent damage from excessive heat.
- AutoShutDown can be disabled by pressing the [ H ] key. This allows the asset to continue to operate. It also unlocks the asset's weapons that would otherwise be unusable when at high levels of heat. It also increases the amount of damage that heat sinks take when overheating.
- AutoShutDown is a toggle - pressing it a second time will disengage the override.
(bypassing AutoShutDown and crossing the upper temperature threshold, will cause the unit to shutdown and remain energy less for 2 seconds while inflecting damage to your unit.)
- Alternatively, find cover and stay there until your asset cools down.
- All assets in MWLL (with the exception of the Anubis and some Archangels) come equipped with a limited supply of coolant. You can perform a coolant flush by pressing the [ C ] key, which will rapidly reduce some of your heat. Coolant works like a heat exchanger and functions most efficiently when the heat bar is high. Beware of lava, using coolant in lava will heat up the asset instead of cooling it.
- Utilizing the Chainfire fire mode can help curb heat spikes from firing high-heat weapons.
- Also, if there's a large body of water nearby, jumping in will aid your heat efficiency depending on how immersed in the water you are -- if the water completely covers you, your heat dissipation increases dramatically.
- For assets with many, smaller high heat weapons, like Heavy Medium Lasers, it is most heat efficient to chain fire and keep the heat level close to the yellow line. This will maximize heat dissipation and maximize DPS, all without causing major damage.
