In Portal Knights you can choose to play alone and enjoy the beautiful [[Islands|environment]] all by yourself, build your home and explore [[The World|the world]]<br>
or to play with up to
3 friends in a 4-player group to have fun together. But on xbox one, players cannot be on different islands. <br />
Some content is nearly only accessible through a group or very hard, like Hard Mode [[Bosses]], and the game overall is a lot easier within a group.
