Nutrient Block Guide

Inventory icon

The starter locker gives you emergency food for the opening material trips. Carry a block when leaving the Lifepod and keep the rest for the next dive.

Quick answer: Nutrient Block is starter emergency food. The current First Hour route records three Nutrient Blocks in the default locker, with each block restoring 40 food. Use them to stabilize the opening material loop, not as an excuse to ignore later food and water systems.

Count the blocks

The starting supply locker contains three Nutrient Blocks and one Aid Kit.

Step 3

Spend them slowly

Each Nutrient Block restores 40 food, so three blocks are enough for the first material phase.

Step 4

The blocks buy time; they are not the long-term food and water plan.
