Based on Irish mythology, The Arrival is a unique area control game where the players claim territories and can also cause more and more enemies to spawn on the board taking corruption in the process. The game has two different ways to score at the end depending on who is most numerous at the end of the game - the players or the evil Fomori.
The most unique aspect of The Arrival, is the way players get resources over the course of the game. Each player will select four cards that only have vague hints on what is on the other side to decide what resource they will receive. Each card has three rows on it and players will have to select which of those rows they want to collect from before they have seen the flip side on all four cards.
Once everyone has gotten all of their resources, players go around the board taking actions. They can build up strongholds, place defense in their regions, fight off the Fomori, and finally place more Fomori on the board. When doing that you are able to have them attack other players destroying some of their strongholds. Although that is also giving them monsters that they are able to attack for points later!
The game ends when one player has become too corrupt from helping the Fomori, or after a certain number of rounds have passed. If the evil outnumber the strongholds on the board then they have overrun the players and the person with the least corruption wins the game. If there are more strongholds than evil, then players calculate who has the most valuable areas under their control making your path to victory an interesting balancing act.
