Publisher's blurb: The Environmental Guide is a rulebook intended for Game Masters, allowing those who wish to run a more survival-oriented campaign to throw challenging obstacles at their players. Instead of providing a list of obstacles or points of interest that one might run into in the Matoran Universe, this guidebook is instead a modular system that allows Game Masters to build up the Matoran Universe from the ground up, region by region, until the entirety of the world can be fleshed out for their players to explore.
