Rolling Thunder/Stage 1

Welcome to the game. Once Albatross has appeared on the screen, start walking to the right and shoot the first two Pink Type 1 Maskers. An Orange one will come out of a door after you have killed them, and two more Pink ones are present on the platform overhead. Just before the first ammunition room, there is another Pink Type 1 Masker and a Yellow Type 2 Masker (the latter of which takes two hits to kill). Once you have obtained the extra ammunition, jump over the crate and shoot the next two Yellow Type 2 Maskers who have emerged from the doors, along with two more Pink Type 1 Maskers. Just before the first Machine-Gun Bullets room, you will have to jump over another crate with an Orange Type 1 Masker and a Yellow Type 2 Masker on the other side of it, and there are at least four more Pink ones on the platform overhead. Once you have obtained the Machine-Gun ammunition, jump up onto the overhead platform and walk off its edge in order to get past the two crates stacked on top of each other. You will now have to deal with two more Pink Type 1 Maskers, along with an Orange one and a Blue Type 2 one who have emerged from the doors. On the next overhead platform, there are two more Pink Type 1 Maskers, along with an Orange one, a Gray one and a Yellow Type 2 one; jump up and shoot them before they have a chance to shoot you. Once you have done so, collect the extra pistol ammunition from the third door along on the platform. After this, continue walking to the right until you fall off the edge of the platform. There is a Gray Type 1 Masker opposite you - once you have disposed of him, keep dropping down off the platform edges until you reach the bottom. Two Pink Type 1 Maskers will emerge from the doors, along with an Orange one and two Blue Type 2 ones. Soon after, you will come to a stack of tires with a Pink Type 1 Masker and a Blue Type 2 one hiding behind it; shoot them before they manage to shoot you and continue on over the sandbags. You will now see four Orange Type 1 Maskers and two Yellow Type 2 ones jumping over the subsequent tire stacks in your path - try to kill them all before they manage to reach you. Towards the end of the stage, you will have to traverse a giant platform made up of sandbags which has several varieties of Maskers on it. Once you have killed them all, made it to the other side of the sandbag platform and entered the doorway, you will proceed to the second stage.
