Marine Block Map

Adventure Maps / Survival Maps




It’s Skyblock... but you’re underwater.
Marine Block throws you into a whole new survival twist — no surface, no land, just ocean above, and pressure all around. You spawn on a tiny underwater island with a single tree, a chest of basic gear, and one goal: survive and beat the Ender Dragon... without ever going up for air.

Use doors, trapdoors, or signs to create air pockets and slowly expand your base beneath the sea. Just like Skyblock, you’ll need to craft a cobblestone generator, manage every block, and think way ahead.
The difference? Everything’s underwater — and it changes the game completely.

🔹 End Portal Island: Unlock the End and prepare for the final boss fight.
🔹 Obsidian Island: Grab obsidian to build your Nether Portal and start the blaze grind.

It’s creative, brutal, and weirdly peaceful at the same time.
If you love Skyblock but want a fresh challenge? This is it.
