Description
Welcome to Hay Hay Studio. We've been expecting you. On your journey here to this group, you have probably fought some creatures before going to this group. Also have a nice stay! Also The UnderGround Facility is made by Hay Hay Studio! It is not a copy or a remake of The UnderGround Facility by LAMINAX CO.! This game is different in a lot of ways! Rules: *Don't Demand for Updates, as they take a while to make. *Don't use foul language. *Don't be mean to the Owner, HeadAdmins, Admins, and or each other. *Please be respectful of one another. Breaking any of the rules will result in a Ban. You could also join our other group, Hay Hay Towers of Hell. We really need players in Hay Hay Towers of Hell because we've been losing players for the past months, and that game I have worked on the most out of any other game I have made.
