Sky Nations is a multiplayer sandbox game where players can join together to build air ships(cannons and all!) and do battle across a vast world procedural world full of relics and machines from another age waiting to be plundered by daring sky captains and their motley crew.
To create power on ships you must use generators. The lowest tier of this is the mass generator, which burns most items to create power.
