New achievement! Complete failure. You failed the quest less than five minutes after receiving it. What talent! A flying fortress occupied by dwarven warriors. Sand castle. An abandoned submarine guarded by faulty machines. A haunted crypt surrounded by deadly traps. This should be easy. One bubble. Four castles. Fifteen days. Capture each one and the stairwell will open. That's the problem. It's never easy. Karl and his team can't do it alone. Not this time. They have to rely on the help of low-level crawlers trapped in the bubble with them. But can they be trusted? Welcome, crawler. Welcome to the fifth floor of the Dungeon.
