From Wizards of the Coast website:
A cooperative game of adventure for 1-5 players set in the world of Dungeons & Dragons.
A heavy shadow falls across the land, cast by a dark spire that belches smoke and oozes fiery lava. A cave mouth leads to a maze of tunnels and chambers, and deep within this monster-infested labyrinth lurks the most terrifying creature of all: a red dragon!
Designed for 1-5 players, this boardgame features multiple scenarios, challenging quests, and cooperative game play.
Dungeons & Dragons: Castle Ravenloft Board Game
This is a players vs. the system cooperative game of dungeon crawling and combat. Players choose from 5 different characters each granting a unique ability to the group. Players will select a scenario to play through which will determine the starting position of the board and set out the victory conditions. The map is randomly determined by using a set of square tiles, ensuring that each tome the game is played the experience will be different.
When monsters are revealed a card is drawn and a figure is placed on the board. The monster's card determines how they act when activated, by listing their tactics. Players who found the monster "own" the monster and only activate them at the end of their turn, or if another player has an identical monster. The players lose if anyone dies, and with only 2 healing surges available that is a likely outcome. The game is challenging but not insurmountable nor formulaic.
