Gloomhaven is a Euro-inspired legacy dungeon run game with a rich fantasy themed background filled with untold lore. Players will embody the role of adventurer from different races who carry various skill sets (Brute, Cragheart, Mindthief, Scoundrel, Spellweaver, Tinkerer). Each team (up to four characters) will band together to explore the ends of the world, all with their own secret objective in mind. You will encounter many events that test your morality, explore a number of dungeons fighting countless monsters, nefarious beings and mythical creatures all while trying to sneak out with loot that spill out of your tiny bags and shallow pockets.
Each scenario is unique all while consistenly flowing from one situation to another. Players will decide how they want to proceed and where they want to proceed to. The main highlight of the game is the innovative combat mechanic involving cards and hand management, which promotes strategical thinking and minimises the variance of luck. Every player enters a scenario with a variable but limited card pool - movement, combat and other assortment of skills are activated by playing two cards at a time. But the turn order is also determined via the initiative number visible on these cards. Each card will contain two parts - a top skill and a bottom skill. Once the card are played you must choose the top skill of one card and the bottom of another. Monster combat is determined by the monster decks, each being unique to the class of the monster with an implement and well designed AI system. Attack skills may be enhanced or debuffed according to each players' modifier deck, as well as monsters. Once a card has been used it is discarded but as time goes on, your cards will become lost (removed from the scenario) until at last you run out of cards and become exhausted and your character is also removed from the scenario (taking lethal damage will also cause this).
As you progress through the game and gain experience, your character will level up and being beefier, have access to more skills and your modifier deck will be upgraded. In certain cases, once your character has seen much of the world, he is able to retire unlocking deeper secrets of the game.
