Gauntlet on the Ice is a short, two page adventure in which the characters are travelling on a frozen lake, perhaps one they have been forced onto, when they are attacked from below. They have to contend with difficult conditions whilst under attack.
This is aimed at d100 systems but is generic enough in nature to be adapted to others.
This PDF supports Adobe layers and the page backgrounds and images can be disabled to make printing easier.
The adventure comes with an 18"x18" square battlemap of a frozen lake taking up six pages that can be printed out and assembled.
One page is cover, one the front matter and one instructions on assembling the battlemap.
