How to Play Master of Monsters
Quick start
Start Campaign 1 or 2, choose a master where the mode allows it, and summon an affordable first line of monsters near your fortress. Capture towers to expand the unit limit and income, use terrain for protection, and keep the master screened from direct attacks. End each turn only after moving units and considering one spell or elemental Force action.
Controls
D-pad: move the map cursor; hold B while moving for fast scrolling. C: confirm, select a monster, destination, or target. B: cancel or return. A: open the main menu for Summon, Magic, Force, unit table, setup, or End Turn. Start begins from the title screen. Battles use the same cursor-and-menu controls.
