This adventure is a TREAT for both the GM and the players - leaning hard into Blade Runner both in aesthetic and theme makes for a delightful romp through a thoroughly well-crafted story filled with moral complexities and complicated alliances.

True to form of his previous adventures, Anthony turns player agency up to maximum here, with combat situations being extrapolated to the point that the sky is quite literally the limit when it comes to how to resolve them. This could, in newer, unexperienced GMs hands, create a problem at the game table, but Anthony does a great job of conveying not only the mechanics at hand but the intent behind them so it's easy to grok why he's written the scenario the way he has, and leaves GMs room to interpret the situation into whatever methodology they find most comfortable.

The story and characters are varied and colorful, and the inclusion of all of the art assets enables you to really paint a picture for the players that makes following along not only easy, but desirable and stimulating.

I'm not knocking a star off for it, BUT: the final encounter may not be balanced adequately based on the standard "very weak-very strong" scale - the dragon breath attack is a strong potential one-hit-KO for many characters who are below the optimized APL of 8 (since it kills outright when a character drops to 0), and the "Weak" bracket (being the thing you will likely encounter most often in a mixed party larger than 3-4 characters, as is common in AL) does not account for this adequately, since the attack is still available at the outset of the fight and is almost certainly the first thing the dragon will do given the opportunity, particularly if the party rolls poorly on initiative.

GMs (and the author) might consider simply applying the Potion of Heroism effect directly to every character by default when they enter Ios, rather than give them a single potion to use, or tune down either the damage or DC on the breath weapon - something in the range of DC 15, and/or damage in the 40s. Unfortunately I wasn't so lucky in foresight as I don't play PCs enough to have a strong grasp of their HP ranges, and I obliterated two of them on the spot, and prompted the other three to quickly high-tail it out of the scenario, leaving Ios to their fate.

All that said, I do want to reiterate that this is an EXTREMELY high quality adventure, well worth your money and time. It's full of great ideas and even makes me want to make a cyberpunk psionic character now. :)
