This was a very solid product, a perfect side-trek adventure or one-shot session for mid-heroic tier play. A friend of mine wanted to try the DM seat out for a night so I pulled this baby off my computer, printed off the dungeon tiles from Skeleton Key (made specifically to be used with this adventure, but they still have applications elsewhere) and we had a blast. In fact I'd say bashing in ant brains was one of the most entertaining nights we ever had playing 4th edition.
From the start with a crazy alchemist begging for your help all the way to the deadly fight with the Queen Ant this two encounter adventure is absolutely perfect for a one-night session. It took just over four hours to complete, mostly because we spent a lot of time goofing off and enjoying it.
If you ever need a short adventure, something to buy time until you finish that adventure against the dragon or whatever it happens to be and your characters happen to be between 4-6th level, this is how you are going to entertain them and still have time to work the kinks out of your own adventure. It comes with everything you need to play, including counters for the various monsters you will fight, and if you get the bundle you also have dungeon tiles that are near perfect replica's of the maps in this product.
An amazing value and hopefully they will continue to put out more side-trek adventures a niche that is sorely lacking in Dungeon these days.
