How to build with the Base Building Plus (BBP) mod on XDC — workbenches, crafting kits, upgrading through the tiers, Tier 3 permits, cement mixers and base persistence.

XDC's custom Base Building Plus (BBP) material costs — the full per-stage cost of every wall, floor, roof, door, gate, hatch, window, stair and pillar, tier by tier.

Building an underground base on XDC — digging the hatch, upgrading through the tiers, securing it with a codelock, plus the base-lag safety tips, persistence rules and how it's raided.

How flags and territories work on XDC — building a flagpole, refreshing nearby items, claiming a protected territory, member ranks, leaving, outsider ejection, raid rules and repairing your base.

How long items last on XDC before despawning — the 45-day timer on base structures, what counts as interaction, how flags refresh items, and the persistence of storage, shelters, stashes and vehicles.

How raiding works on XDC: vanilla bullet and explosive damage on both vanilla and BBP bases, breaching and vertical charges, tier HP, and how many charges, grenades or bullets each tier takes.
