Since at the moment the game picks up Oberon-1 is in highly distressed state, naturally the internal and external ruptures are causing great difficulty to not only navigation, but Sean's health as well. Depending on the hazard severity, there are two types of markers, different by the range and damage caused:
- Sone hazards take away 20 HP within the proximity of 20 units; (prevalent on all difficulties)
- Sone hazards take away 35 HP within the proximity of 35 units. (prevalent on higher difficulties)
The best way to evade the hazards is to use Diving Mode. These markings appear only when the player is underwater.
