Ethan's Journey Through the Virtual Frontier Chapter 18

The rule for passing a level is that the first 100 planners will all pass, and as long as they persist for 48 hours, the survivors who are still alive will not be eliminated.

But apparently someone doesn't think so.

Or maybe some people's pursuit goes beyond this.

The only survivor.

When the countdown ends, if only you and your team members survive in the level, and no other planners survive, the mission is completed. You will get the level's special SSS reward.
