Underwater Survival is a survival map featuring 26 underwater domes, 6 dungeons, and a staggering 70 quests. Designed for 1 to 3 players, it is meant for fun and for those who want to experience survival gameplay with a fresh twist—and for much longer than a measly 10 hours. There are 4 dungeons in the Overworld, plus one each in the Nether and the End.
