Our first play was ... interesting.
4 players, one of each base game class (I only have the 2nd ed box, plus all of the 1st ed stuff except Sea of Blood) Found some characters still missing from the app.
Small winding cavern with a boulder and a cave enterance that had to be blocked with said boulder, and a large Kobold group blocking the way.
The kobolds respawned a bit due to their skill test at the start of their activation, but it constantly told me to put out 3 Ferrox by the cave enterance every round (which I did not do, we were swamped already with the initial Kobolds and Ferrox)
By the time we cleared the Kobolds we had lost due to losing Morale for taking too long, on the first map.
Was an interesting experience, will try it again but yeah, didn't see any way to get through it in time.
