I bought this product at the full five dollar price. I too snapped it up...and immediately suffered from buyer's remorse.
I still don't know if it is worth two dollars.
Showdown is a table top miniature wargame, and a good one.
I was disappointed that Warriors did not have an army list (just something typical not definitive).
I was disappointed that it did not have a generator for scenarios or any campaign suggestions.
The scenarios are pretty generic. It would have been nice if they would have been tied to some sort of campaign or something from Mars RPG setting.
It does have an exhausting (if not exhaustive) list of different types of soldiers...but no info on how they are deployed or used.
There are tables that are useful. There are new weapons and edges that are actually new and not rehashes of old stuff.
