The box itself looks solid, the maps are very well made. What's to complain about at this Munchkin however, is the game. The "forces" provide for a rapidly developing imbalance in combat forces. At the same time too little monster amplifier cards are available to actually munchkinly force to his opponents in the fight against a monster to escape.
For Munchkin newbies I would not recommend this game, but for Munchkin Experienced who might want to pick a few specific cards from the deck to expand their overall game, it can be very interesting.
