How to Excavate Ocean Ruins Faster with SUS Blocks

Underwater archaeology in warm and cold ocean ruins is difficult due to low visibility, water fog, and drowned mobs. Using the SUS Blocks Resource Pack lets you quickly scan the seabed and target only the blocks that hold loot.

Scanning Warm and Cold Ocean Ruins

1. Swim down to an ocean ruin structure. Warm ocean ruins generate with suspicious sand inside sandstone structures, while cold ocean ruins generate with suspicious gravel.

2. Before digging into the seafloor, swim around the perimeter and peer into the ruin openings.

3. Look for the bright red crewmate icons contrasting against the pale sand or dark gray gravel.

4. Because the red marker stands out clearly underwater, you do not need to get right next to every block to inspect its pixel pattern.

Clearing Hidden Layers

Many suspicious blocks in ocean ruins are buried one or two layers beneath regular sand or gravel.

1. Equip a shovel and dig away only the unmarked surface blocks around the structure walls.

2. Watch each newly exposed block face as you dig—the moment you see a red crewmate icon in the corner of a revealed block, stop using your shovel.

3. Switch to your brush to extract the treasure before moving on to the next marked block, minimizing the time you need to spend underwater managing your oxygen bar.
