Number of stages: 7
Round 7 features a total of 7 stages, making it the largest level in this prototype.

The first stage features a large house, which contains some ninjas and soldiers, many of which are stuck in the walls or floors. Move through the house and head right to drop down onto a floor. Run across this to finish the stage.

The second stage seems to take place in another house, with lots of steps to climb and descend.

There is one part where you'll have to spider-walk to get across. The only enemies here are some soldiers, and when you reach the point in the above right image, drop down to complete the stage.

The next stage has two routes. When you reach a small bridge, you can either cross it, or drop down under it.

If you go down, you'll enter an underground area which has a few platforms to leap across along with some solider enemies. If you cross the bridge, you'll come across another house, which you can run through, but watch out for the ninjas.

The next stage has a different background, featuring the moon. The enemies here are soldiers, many of which are placed in walls are just in the air.

Jump across to the right to enter another building, which doesn't have much in it other than a few soldiers. When you come to the end, you'll see a small platform in the middle of the air. Jump or move right towards it to finish this stage.

The next stage is a lot like the previous one, but now with ninja enemies in it.

The sixth stage is the shortest one in the game. You'll drop down into it, and all you have to do is walk right for a couple of seconds to complete it.

The boss of this round is the final boss from The Revenge of Shinobi. Like the previous round's boss, the background for this stage hasn't been completed, and just features some garbage sprites for the floor. The boss has some sprites that were possibly used in the original version, but were not used in the final game, such as him fallen over. The round clear art for this level is the same as what the first round uses, but colored purple.
