Rolling Thunder/Stage 9

You may think that this stage will be similar to the fourth one (except with more enemies), but it isn't. Once Albatross has reappeared, jump onto the overhead platform, start walking to the right, make a short jump over the gap and shoot the Brown Type 2 Masker once you have landed on the other side, along with the Gray Type 1 Masker and the Fire Man (the latter of which will split into three when hit). Shortly after, there is a laser on the ceiling which fires beams down regularly; you will have to pass under the laser when it is not firing in order to avoid being hit. Once you have done so, there will be another Brown Type 2 Masker and Gray Type 1 Masker to contend with, along with two Green Type 2 ones at the top of a staircase. Once you have jumped up to the top and killed them, another one will emerge from the door and follow you as you drop down off the edge of the staircase in order to land on an overhead platform below (where a Purple Ninja will materialize from the wall). He takes four hits to kill, and the door on the left ledge below is a pistol ammunition room. Once you have dropped down and obtained the extra ammunition, two more Purple Ninjas will materialize from the wall. You can either drop down to the right ledge below or all the way to the bottom if you want to save some time after you have disposed of them. A Yellow Ninja will materialize from the wall once you have done so (who will only take two hits to kill), and there are two more lasers on the underside of the right ledge firing beams down regularly. You will have to pass under both of them when they are not firing in order to avoid being hit this time. Once you have done so, another Yellow Ninja and another Purple Ninja will materialize from the wall. You will also have to deal with an Orange Type 1 Masker, a Gray Type 1 Masker and a Blue Type 2 Masker just before passing under another ceiling-mounted laser. Just before a Machine-Gun Bullets room, there is yet another ceiling-mounted laser with a Green Type 2 Masker, a Blue Type 2 Masker and a Gray Type 1 Masker on the other side of it. Once you have bypassed it, killed the Maskers and obtained the extra ammunition, there is another Gray Type 1 Masker just before two more ceiling-mounted lasers (the one on the left fires down longer beams than the one on the right, so good timing will be essential to getting past them). Soon after, there are two more ceiling-mounted lasers firing beams down onto the platforms overhead, with two Orange Type 1 Maskers and two Blue Type 2 ones below them. A Yellow Type 2 one will also emerge from the door once you have killed them all, and there is a laser on the underside of the last overhead platform firing down very short beams. Once you have bypassed it, you will have another Orange Type 1 Masker and two more Blue Type 2 ones to contend with just before another staircase with a drop down to the ledge below once you have made it to the top. After dropping down to the left in order to land on the next ledge below (don't worry; a Masker will not emerge from the door on it), you can either drop down to the left or right in order to land on either of the next two ledges below, then down the gap in the centre in order to land on an overhead platform (where a White Ninja will materialize from the wall). He will take three hits to kill, and the door on the left ledge below is a pistol ammunition room. Once you have obtained the extra ammunition, drop down to the right in order to land on the next ledge below. Three more White Ninjas will materialize from the wall as you do so, and the door on the ledge is another one from which no Maskers will emerge. On the underside of this ledge, there are two more lasers firing beams down regularly; once you have dropped down to the right, landed on the next ledge below and bypassed them, two more White Ninjas will materialize from the wall. Towards the end of the stage, you will firstly have to deal with a Fire Man and a White Type 1 Masker just before two more ceiling-mounted lasers (firing very short beams again); secondly, you will have to contend with an Orange Type 1 Masker and a Blue Type 2 Masker; and finally, you will have to dispose of three more White Type 1 Maskers, a Brown Type 2 Masker, another Yellow Ninja and two more White ones who have materialized from the wall, along with three Gelzos who have burst out of the ground. Once Albatross has entered the doorway on the right side of the screen, he will proceed to the tenth and final stage.
