RIVER OF FIRE – The Nether is a place of scarce resources, but one thing is abundant: lava. All those who want to survive must find a way around its scalding surface. Finding a safe path to reach your goal is not for the faint of heart or those afraid of a little hard work.
— In-game description
The Nether Fortress before you is protected not just by walls and fortifications, but by an endless supply of deadly lava. Your only hope is to find a safe path that leaves you unscorched and ready to face the challenges within.
