A cooperative game in the theme of the Kids' series Night's Watch ("Nachtwacht"). Somebody opened the gates to the underworld. Monsters have free reign. The heroes of the Night's Watch are their to combat them, together. They patrol through Twilight Town by rolling the "walk die". By being attentive during their patrol (a 1/3 chance roll of the "walk die") they can gather skills (up to 5 skill cards). When on their patrol they encounter a monster they have to do a skill test. If they pass (roll 1 of the remaining skills required OR use the proper skill card), they hurt the monster. If they give the monster the final blow, the monster is defeated and removed from the board. If they fail, they loose health points (1 of 3). Incapacitated heroes can still help the party with their skill cards. The Night's Watch wins if the monsters are all removed. However, the monsters win if EITHER all heroes are incapacitated OR no more skills can be learned (a skill card must be drawn but all skill card deck is empty).
