The High Command offers a choice of territories.
Harvest the spice, build your base, destroy the enemy. Each mission the Mentat briefs you; early missions ask for a spice quota, later ones for total war. The screen is the original: MENTAT and OPTIONS up top, your credits at the right, the build window and radar on the side panel.
Click a unit to select it — then click the map to move,
an enemy to attack, or spice to harvest (the side panel also has ATTACK / MOVE /
GUARD buttons)
Click a building to select it — factories and the Construction Yard show
their production in the side panel: pick an item with < >, press
BUILD, then PLACE IT and click the map

Build windtraps for power, a refinery for harvesting (it arrives with a free harvester), silos for storage. Buildings need rock or concrete slabs, near your base. Watch for sandworms — they eat vehicles whole. Progress and saves stay in this browser; you must own an original copy of Dune II to play.
