Become a Gnome
Prepare to invade the houses of unsuspecting humans along with up to 5 friends of your choice. After finding your way in, take anything you want. Human laws don't apply to gnomes! Just try to be stealthy...
Do your job
While burgling is a very productive activity on its own, you also need to do your job. The High-Gnome won't transport you around for nothing, so you must complete tasks for him to stay on his good side! Failing to complete enough tasks might get you fired...
Craft and Upgrade
Some of the stuff you find is useful as is, however a certain amount of repurposing is often needed to fit the specific needs of gnomes. Craft equipment, build functional furniture, and upgrade your home with the burglin' haul.
Stay safe
Gnomes are small and fragile, and often hunted by other beings. Interact with the environment and use your equipment to slow down any hostile meanies. Stay vigilant, and be ready to rescue one another. The High-Gnome doesn't like resurrecting unworthy gnomes...
