The Invitation is a three to five player cooperative tabletop game where the players explore a derelict mansion and fight to avoid madness while completing the chosen scenario. Each scenario presents a plot, objective, and special rules for the gameplay. Certain scenarios introduce special mechanics that change the dynamic of the game. For example, the second scenario introduces a traitor mechanic in which one player secretly works against the rest of the players to accomplish his/her own goals. The exploration of the house is based on a randomly ordered deck of Room Tiles, so each play through is different in how the house is laid out. Items, enemies, and events are also encountered in a random order, which also serves to differentiate each play through and adds to the replayability. —description from the designer
