Bleeding out. Your squad can get you back up: hold on.
YOU WERE OVERRUN
The Ark's ferry crew dragged what was left of you back aboard.
DEAD TIDE
The island fell in a week. The Ark still floats.
Take contracts from the Ark's command, ferry out to the island, scavenge, fortify, and survive the hordes.
When they can't reach you, they'll tear through the doors and windows. Keep planks on you.
