Going through the door on the right, followed by the next door, will take the player to a conveyor belt with spikes above it if the player is powered-up, they will have to crouch under them. Dropping down through the gap and trying to jump out will reveal Hidden Blocks, with the right-most one containing a 1-Up Mushroom. Continuing over the lava, the player will come to a brick wall with a ? Block containing a Starman next to it.

The door under the Thwomp will also lead directly to a 1-Up Mushroom. The next four doors lead to the same large room, though if the player finds the Switch Block in the Brick Block formation from earlier, there is a secret door that leads to a 1-Up Mushroom. Back in the first room, there is a door surrounded by Brick Blocks, and going through the door will put the player on a conveyor belt over lava. The door above and to the right of the power-up will lead to a room with another Fire Flower, though the player has to first reveal Hidden Blocks to get to it while avoiding a Thwomp. Continuing from the Roto-Discs, the player will find a Brick Block containing a Fire Flower.

The player starts next to some Roto-Discs, above the third of which is a door that leads onto a conveyor belt over lava, which leads to a power-up with a Super Leaf. It is the longest and final fortress in the game.ĭark Land's fortress is made up of many doors and traps. It becomes accessible after the player clears World 8-2 and its own completion opens World 8. World 8- Fortress is the fortress level, and the ninth level overall, of Dark Land in Super Mario Bros.
