Build a base. Break into theirs.

Place a flag to claim a zone. Only its owners can build or dig there, plus their guild if they share it.

Hold a hammer and press B. Foundations, floors, walls, half walls, windows, doorways, stairs, ramps, hatches, railings, roofs, pillars and beams all snap to each other. On a slope you can raise a foundation so the house stays level.

To take down a piece of your own, hold the destroy button with the hammer and it comes apart in a few blows.

Hold attack on a piece with your hammer to upgrade it to the next material. Each one holds out longer than wood by about this much.

Single doors come in every metal. Double doors come in wood and iron, and you'll want one if your horse is coming inside.

A hatchet works on wood. Stone and metal need a pickaxe and a lot of patience. Bombs and dynamite from the alchemy table are much faster.

A Common bomb hits for 500, a Legendary one for 1,250, and dynamite for twice that. The blast hurts anyone standing too close, including you.

Your character sleeps where you logged out, and sleeping players can be killed and looted. A sleeping bag sets where you come back after you die. A Crude one makes you wait 3 minutes, a Legendary one 20 seconds.
