In Dungeon Crawler ECG your party of adventurers face off against terrain, traps, events and characters using equipment, magic, skills and tactics to try and complete 2 out of 3 quests or just to survive the dungeon! Each round cards are drawn from the dungeon to face off against, and the player must strategize the best way through each encounter. This game starts off in Story Mode, but can expand for Multi-player. The Thorn really adds some brutal combinations to the mix! This expansion focuses on an undead lich named Zhuldar that has awakened. The heroes are on a quest in to the elven forests to face him in his tower; the Thorn. The Thorn introduces a new Adventurer (Keldornan Druid), a new Quest (Seen It All), 16 new crawler and dungeon cards. The expansion totals 82 all new cards with 34 new pieces of art and two Resource tracking cards. This is not a game in itself, but an expansion pack.
