While these ”golden worlds“ show promise of human colonization, most are still environmentally hazardous, with the potential to kill the reckless. There are several types of global hazards, each having varying levels of severity, displayed at the bottom left of your HUD. The higher the severity of the environment you’re in, the faster your life support gauge drains.
Life support can be restored through various means, depending on hazard type. For instance, if you’re suffering from extreme cold on Voeld, you can find an installed heater to warm up.
Level 1 hazards are generally manageable for long periods of time. You can usually explore and complete objectives under Level 1 severity.
Level 3 and 4 hazards drain your life support extremely quickly. This usually means the area is off-limits until the severity declines (either through activating vaults or progressing through the main story).
