Arkham Horror is a cooperative board game for one to six players who take on the roles of investigators trying to rid the world of eldritch beings known as Ancient Ones. Based on the works of H.P. Lovecraft, players will have to gather clues, defeat terrifying monsters, and find tools and allies if they are to stand any chance of defeating the creatures that dwell just beyond the veil of our reality. The game is split into a series of rounds made up of four phases: The Action Phase; The Monster Phase; The Encounter Phase,and ;The Mythos Phase.
The Action Phase sees your investigators fighting back against the dark power of the mythos. During this phase, each investigator can perform two different actions. Move – Investigators can move up to two spaces in the city, spending money to hire speedy transport and move additional spaces. The space where you end your turn will determine what encounter card you draw later in the turn. Gather Resources – Gain one dollar token, which can be used to purchase items and goods as well as increase how far you can move Focus – Focus one of your skills, increasing its value. Ward – Attempt to remove doom from your location. Increasing doom means danger for the investigators, and removing doom can delay these apocalyptic heraldings. Attack – Attack a monster engaged with you. Evade – Try to escape from a monster engaged with you. Research – Search for clues at your location. Trade – Trade money, clues, items, and more with other investigators at your location.
