From the introduction:
Cut your players down to size with Microsized Adventures, by Everyman Gaming, LLC. Designed for the Pathfinder Roleplaying Game, Microsized Adventures gives GMs and players alike the tools they need to create adventures and campaigns from an ant’s point of view, whether the PCs want to mount an ant, scale a dog, or boldly flee from a lumbering toddler.
Microsized Adventures includes:
Rules for altering ordinary-sized creatures in size, transforming them into miniscule Microsized Characters or massive Macrosized Characters.
Rules for adjusting ordinary-sized pests and creatures into mighty threats.
Rules for adjusting combat to accommodate extremely small or extremely large creatures, such as by altering the amount of space conveyed by a square on the combat grid or determining how tiny creatures can make attacks of opportunity, flank, and more.
Two new combat maneuvers that anyone can use, the crush maneuver, which allows large creatures to stomp smaller foes flat, and the scale maneuver, which allows tiny creatures to climb up larger enemies in order to find the perfect vantage point from which to strike.
New archetypes and class options that utilize the new rules found in Microsized Adventures.
New artifacts, cursed items, and intelligent items that can act as the catalyst to a Microsized Adventure.
