How many times have you expressed (or seen expressed) the desire to watch seasons change in an MMO? That’s not a feature that most titles provide, but it will be part of the landscape of Life is Feudal.
In the sandbox’s newest patch, Life is Feudal has added art for all four seasons. Will seeing the land transition from winter to spring be a small but helpful tool for immersion? Its testers will soon find out!
The patch also contained an herb garden for alchemists, settlement decorations, an auto-repeat function, and some changes to boost the frame rate. You can snap up Life is Feudal for $12 as part of the current Humble Bundle.
