V3.0 Sandbox Settings Guide

Change one pressure system at a time, record the baseline, and keep your calculator inputs aligned with the world you actually play.

Updated July 30, 2026V3.0

Start with the experience you want

V3.0 exposes a much broader set of sandbox controls. The useful question is not “what is the best setting?” but “which pressure should this world create?” A builder world may keep enemy block damage low while preserving dangerous combat. A short co-op season may increase experience and loot while making Blood Moons more frequent.

Settings that change our calculators

Setting familyAffectsPlanning response
Blood Moon frequency and enemy countHorde duration and simultaneous pressureMatch the enemy count and manually add reserve for shorter cycles.
Zombie block damageRepair materials and failure speedAdd a larger repair reserve and a second structural layer.
Loot abundance and respawnSupply route valueCompare routes, but do not treat quality bands as guaranteed.
XP multiplierLevel and skill point timingThe skill planner still counts points; the calendar time to earn them changes.
Party range and shared progressionCo-op game stageUse the highest active player as a conservative horde input.

Three practical profiles

Solo builder

Keep standard day length, lower block damage slightly and retain normal loot. This gives building experiments room without removing resource pressure.

Four-player weekend

Increase experience and loot modestly, keep horde count within server performance limits, and make the night dangerous through speed or damage instead of an excessive active cap.

Long survival season

Use slower progression and longer loot respawn. Keep a written world profile so tools and saved blueprints remain comparable after updates.

Version discipline

After a game update, confirm the displayed version in the main menu or server logs. Then review official release notes and recheck the settings that alter progression, loot and spawning. Blood Moon Lab displays its current data profile on every calculation page.
