This scenario has promise, but lumps a lot of very dangerous, nigh impossible to detect or stop effects together with 2 tricked out combats in the same essential location. The first can be debilitating, but you are punished if you don't go straight to the 2nd quickly right afterwards.
Scenarios should challenge players, not actively try their best to murder them.
It was short, painful, and not that fun. Interesting setting, but poor development. Overall, there was too little interesting and fun parts, and the last 2 encounters are a bit much.
