Survival missions that take place in Dark Sectors can only be reached by Solar Rails and always involve the Infested. These Survival missions have a higher level range (and thus, higher difficulty) than the planet they're found on, but give out larger quantities of experience, including the experience bonuses inherent in Dark Sectors. There are currently 10 Dark Sector Survival Missions, one each for every planet except Mercury, Earth, Europa and Pluto.
When the life support system reaches 0%, if extraction is not available yet, the mission ends in failure. Otherwise, all squad members' shields will start draining followed by their health, in a manner similar to a hull breach but at a much faster rate. The health drain will stop at 5 HP for 5 minutes – making any damage lethal – and teammates who are killed can be revived normally. No more life support capsules will be dropped, rewards will no longer be given, enemies will stop dropping the life support modules, and all remaining life support modules on the map will become unusable. After this point the mission can still be completed if at least one player reaches Extraction. However, if all players die, the mission will fail. After 5 minutes, the health drain will continue past 5 HP and will kill everyone.
When I visited Johnson, not long ago, at his office on Park Avenue South, he described himself as an accidental student of civic anxiety. He grew up outside Detroit, in Grosse Pointe Park, the son of a doctor, and he watched his father’s generation experience the fracturing of Detroit. “What I’m seeing now in New York City is sort of like old music coming back,” he said. “These are friends of mine. I used to live in Belle Haven, in Greenwich, Connecticut. Louis Bacon, Paul Tudor Jones, and Ray Dalio”—hedge-fund managers—“were all within fifty yards of me. From my own career, I would just talk to people. More and more were saying, ‘You’ve got to have a private plane. You have to assure that the pilot’s family will be taken care of, too. They have to be on the plane.’ ”
Disrupted access to water, food, energy, or transportation. Substantial and prolonged outages happen everywhere; many of us will experience at least one at some point in our lives. A week without electricity may be just inconvenient and scary, especially in a high-rise or in a seedy neighborhood; but even a single hot day without potable water is universally bad news.
A popular way of guarding against this kind of catastrophe is storing food at home. This is called Long Term Food Storage, Emergency Essentials, or Emergency Survival Foods and there are dozens of companies selling food specifically for this purpose. The best, including those listed below, have great tasting products with a long storage life at a reasonable cost.
