In Bungie’s extraction shooter Marathon, survival is not just about weapons and skill. One of the most important mechanics players must understand is the Oxygen System in Marathon. This system works like a match timer and directly affects how long you can stay alive during a run. If you ignore it, your mission could end quickly.
This guide explains how the system works, how injuries affect oxygen, and how you can manage it smartly to survive longer and successfully extract with loot.
What Is the Oxygen System?
The Oxygen System in Marathon acts like a countdown timer for every match. When you enter a map, your character has a limited oxygen supply. As time passes, this supply slowly decreases.
If your oxygen runs out completely, your character begins to lose health. This means you cannot stay in a match forever. Players must complete objectives, collect loot, and extract before their oxygen supply is gone.
This mechanic adds tension to every run. Instead of wandering around endlessly, you must think carefully about how much time you have left.
How Oxygen Loss Works
The Oxygen System in Marathon is designed to push players to make smart decisions. Every moment you spend exploring or fighting enemies reduces your oxygen supply. Here are the basic rules:
- Oxygen slowly drains during the match.
- Running out of oxygen causes health loss.
- Players must extract before oxygen reaches zero.

Players can find oxygen canisters while exploring the map. These items refill part of your oxygen supply. However, they may be rare or hidden in risky locations. Another option is buying oxygen canisters from the in-game market, but they are usually expensive. This means you must balance your spending with your survival needs.
Injuries Can Damage Your Oxygen Supply
A very interesting feature of the Oxygen System in Marathon is how it connects with the injury system. Certain types of damage can affect your oxygen levels. For example, if your character is shot in the waist area, your oxygen system may be damaged. When this happens, oxygen drains faster than normal.
Other injuries can also create problems during combat. For instance, if your character becomes concussed, the screen may blur periodically, making it harder to fight enemies or navigate the environment. This means survival is not just about avoiding death. You must also avoid injuries that make oxygen harder to manage.
