Re-Logic and Engine Software have revealed a brand new sandbox game in their Terraria series, dubbed simply Terraria: Otherworld.

Featured above, you can view the debut trailer for the game, which is described as yet another open world sandbox, only now fans can expect the formula to be expanded upon.

Instead of taking place in a typical fantasy world, Terraria: Otherworld is set in an alternate dimension within the Terraria universe. Players will be put into a life-and-death struggle to restore a once-pure world, which is now overrun with an evil force that has tainted nature itself.

Further details were not confirmed, but the game will be shown off at Re-Logic’s booth at GDC this year.
