This is my newest one. The overall feel of this one is like an action movie. Maybe more like a horror-action movie, but you get the idea. The adventure is hard core old school. It is compatible with S&W: White Box but like most of the OSR adventures it can be used with just about any rules. The file is a pretty simple affair; 19 pages, line art. So nothing too fancy, but the aesthetic is very, very old school. It looks like something your older brother's friend who was the first kid in the neighborhood to play D&D might have made; only a lot better.
The adventure itself starts with a simple set up and encounter (I like adventures that make the players DO something right away) and then that simple encounter leads to a confrontation with an evil cult. Shenanigans ensue. The adventure takes a few cues from more modern adventures and separates encounters. The effect this has is to keep the action flowing. If this were a movie it would be Raiders of the Lost Ark or, more aptly, The Temple of Doom. At just under $2.00 it is also perfect for an afternoon when you want to play something but don't have an adventure ready to go.
For myself I might make some minor changes here and there. Snake Goddesses are fun and all but what if I need a Wolf Goddess or a Centipede one? It make a great introduction for some characters that have already been through one adventure and are their way to the larger plot brewing. I say grab this one and use it this weekend.
