Sector 02 has entered Sunken Veins and is available to work in.
No creatures are present in Sector 02 when playing regularly but you will face other challenges such as toxic gas and an oceanic storm.
Toxic gas creates a time pressure to complete the shift before you choke on the fumes. As you inhale more gas, you also reduce the amount of time you can spend under water.
An ocean storm will occur in sector 02 which causes an overwhelming amount of flooding. Survive by draining away as much of the water as possible until the service lift arrives!
You can add creatures to Sector 02 through the custom game option.
