What is Heat in Marathon? Stamina Explained

Bungie’s Marathon is finally here after an intense and long cycle of development, allowing players to embody mysterious Runners and explore the planet of Tau Ceti IV, filled with UESC enemies. As is the case with most extraction shooters, Marathon features intricate gameplay mechanics that can not only influence strategies but also impact players’ approach to crafting builds, and Heat is one such feature in the game.

Knowing how Heat works before you head out on your next run can be extremely beneficial. Here’s everything you need to know about Heat in Marathon Season 1, including how it works and how to manage and upgrade it.

What is Heat in Marathon?

Heat is Marathon’s version of stamina, presented as a persistent resource bar that shows how much thermal energy you are generating with your Marathon Runner Shell while operating on Tau Ceti IV. Since your Runner Shell, in the Marathon lore, is a high-performance machine, the more you push it, the hotter it gets.

Once you generate a set amount of Heat, certain actions will be limited, leaving you at the mercy of Marathon enemies. You generate Heat in your Runner Shell with these actions:

• Sprint or Slide: Prolonged high-intensity movement builds friction and internal energy.
• Use Abilities: Using Shell-specific powers (like the Assassin’s Cloak or the Destroyer’s Shield) spikes your thermal signature.

How to Manage and Upgrade Heat Capacity in Marathon

When it comes to resetting your heat meter, the best way to do so is by crouch walking, as that speeds up the cooling-down process, along with making you stealthier and harder to detect. Apart from managing, you can also increase your Heat Capacity through Marathon faction upgrades, modifying Implants, Cores, and even in-game items.

CyberAcme Faction Upgrades

The CyberAcme corporation is one of the many factions in Marathon, and it’s dedicated to Shell utility and Heat management. By completing CyberAcme contracts and earning a reputation with them, you can unlock permanent seasonal upgrades in their progression tree. This includes upgrades like:

• Heat_Sink.exe: A permanent upgrade that increases your Runner Shell’s total Heat Capacity.
• Emergency_Vent.exe: Reduces the Heat Recovery Delay, allowing your Shell to begin cooling down faster after you stop generating Heat.
• Active_Cool.exe: Increases the rate at which heat dissipates once the cooling process begins.

Implants and Cores

While the faction upgrades provide a power floor, what you equip with your Runner Shell with Implants and Cores can enhance your overall peak performance. Implants are universal stat-boosters that can be slotted into your Shell before heading out on a run. You can use the Heat Capacity Implant to significantly increase your upper limit.

Apart from Implants, you can also use Marathon Cores to increase your Heat capacity. Some Shell-specific Cores, like the Adrenal Core or Microjet Efficiency Package, don’t just increase capacity. Instead, they significantly reduce the amount of Heat generated by abilities like dashing or double-jumping, effectively letting you do more with the heat you have.

Consumables and Environment Interaction

Marathon’s gameplay mechanics run deep, as during a run, your heat capacity is also influenced by your choices of consumables and interactions with the environment. While exploring Tau Ceti IV, finding Marathon weapons should not be your only focus. You can find and use items like Cardio Kicks, a consumable that instantly clears your accumulated heat and provides a temporary heat reduction buff.

Additionally, you can also passively manage your heat capacity by standing in water or rain, which significantly boosts heat dissipation. However, it is important to look out for Marathon Shields, which might seem like a good idea at first, but end up reducing your heat capacity as a trade-off for a boost in defensive power.

With this, you should be able to efficiently use and upgrade heat when heading out on a run. Do you like Bungie’s twist on the stamina mechanic in Marathon? Tell us in the comments below!
