Deep beneath the keep of Castle Greyhawk, a really nasty device is creating mutated, unpleasant monsters that are running wild throughout the castle and the twelve-level dungeon beneath. The call has gone out for heroic, fearless, and perhaps foolish adventures to out-hack, out-slash, and sometimes even out-think hordes of doughmen, headless mice, manic bee queens, really bad dead things, burgermen, crazed chefs, and movie moguls. If they survive these and much odder obstacles, the characters still have to find the nasty monster creator and put it out of business. Castle Greyhawkcontains 13 detailed levels for adventuring and exploration. Each is a separate adventure written by different author and each has its own unique brand of baffling weirdness. Some levels involve solving puzzles and some require good old hacking and slashing. The adventure can be played separately or all together as a grand quest to free Castle Greyhawk from the evil, rotten hordes that are plaguing it. The common theme of this dungeon is that no joke is so old, no pun so bad, and no schtick so obvious that it can't be used to confuse and trip up PCs! 13 Adventures for Character Levels 0 to 25.
