Last Haven Bunker

Quickstart

1. Get the tablet — A Bunker Control Tablet is automatically given to you the first time you spawn. If you lose it, craft another at a crafting table:

1. Deploy the bunker — Hold the Bunker Control Tablet and use it (right-click / tap) to open the menu. Select Deploy Furnished Bunker. The bunker generates underground at your current position and you are teleported inside instantly.

2. Manage your bunker — Use the tablet at any time to open the control menu. From there you can teleport back, check status, seal hatches, toggle lights, donate supplies, repair the hull, use the med bay, or redeploy.

Overview

Last Haven Bunker gives you a fully furnished underground survival base that you can deploy anywhere in the world with a single item. Once placed, the bunker runs a persistent survival loop — power, food, and water slowly drain over time, and neglecting them degrades your hull integrity. Keep your bunker stocked and repaired to maintain a safe haven across all play sessions.

Abilities And Mechanics

Resource Drain

Every few seconds the bunker consumes a small amount of power, food, and water automatically. All three resources have a maximum of 100. If any resource runs low, hull integrity begins to degrade.

Donating Supplies

Open the tablet menu and select Donate Supplies while carrying the required items:

You can donate multiple resource types in a single action if you carry all the items at once.

Repairing the Hull

Select Repair Hull from the menu while carrying 6 iron ingots. Each repair restores +30 hull integrity.

Med Bay Healing

Select Med Bay from the menu. Requires at least 10 power and 10 water. On success, you receive Regeneration II for 12 seconds and Saturation briefly. Both resources are reduced by 10.

Sealing the Hatch

Use Seal / Open Hatch to lock down the surface entrance. Seal up before logging off or venturing out to protect the interior.

Lights

Toggling lights off puts the bunker into power-saving dark mode. Toggle them back on to restore normal illumination.

HUD

While near your bunker, the current status (power / food / water / integrity) is displayed on your action bar so you can monitor resources at a glance without opening the menu.

Progression And Strategy

• First session — Deploy your bunker immediately after spawning to secure a safe underground base. Gather coal, wheat, kelp, and iron before your first night.
• Restocking routine — Resources drain continuously. Keeping a stack of coal, wheat, and kelp on hand lets you quickly top up all three resource pools in one trip to the tablet.
• Hull integrity — This is the hardest resource to recover (requires iron ingots). Prioritise keeping power, food, and water above critical levels so integrity never drops in the first place.
• Med bay — A reliable emergency heal if you return to the bunker injured, but it costs power and water, so don't spam it when resources are low.
• Redeployment — Use Redeploy if you want to move your base to a new location. Note it overwrites your previous bunker anchor permanently.
• Hatch discipline — Sealing the hatch when you leave keeps the interior secure and is good practice for immersive survival play.
