The Rubble or Steps is a block placeable by the player in FortressCraft. It is not available in the Block Wheel, however, it can be accessed through the Console Commands with "Fill Rubble X Y Z". This block is not naturally occurring.
This block was released on April 8, 2011, with the release of the game.
It requires a USB Keyboard or an Xbox 360 chat pad to access.
It has the same texture as the top face of grass on all six sides of the block.
If you're using a doorswing block and it doesn't work properly, (you're only using a doorswing and not a dooropen) your doorswing block will to turn into a no clip version of this block.
