Compared to its prequel "Virus", this module shines as a little masterpiece. Context is depicted well and extensively, almost all possible heros' actions outcomes are taken into account both in the global timeline and in the scope of every single encounter.
The plot is thrilling and intriguing and what seems to be a simple race against the clock to salvage a dead alien wreck, turns out to be a perilous situation. Even if your players won't miss breathtaking action, they won't earn their prize without investigation, cleverness and intuition. Most of all, if you as a GM feel comfortable to act dramatic scenes, you'll see you players' faces turn pale in some really touching (and sometimes disgusted) scene.
I really think it's one of the best adventures I've ever run in my life, not to mention it's the best product in RoD series! A must have.
