A rocket blasts off from the lab after Master Contra's base, which is now in orbit. The boosters break away revealing your character strapped to a jet pack.
You will have to fight ten armored enemies before you reach the base (20%). They appear quickly, but only one at a time. Once they open up hit them in the middle with a heavy weapon. If you hit the sides they will take much less damage and possibly fly off before you destroy them.
Boss: Master Contra
- Bill and Jaguar burst in on Master Contra, who despite being annoyed at your survival, decides to tell you what he's doing. He explains how every society has strict morals about not kill, but demands that their soldiers disregard those standards whenever there is an enemy. Contra plans on demolishing all structured society, thus removing the need for soldiers and the inherent hypocrisy that the need for war brings. He doesn't plan on you two living long enough to see this happen though.
When you get onto the base you will have to fight Master Contra three times in the same room. First he will transport around the room swinging his sword (30%), then he will split the sword into multiple blades and throw them at you (40%). Finally he will clone himself and you'll have to find the real one (60%).
Boss: Project C
- After Master Contra is defeated it turns out he was actually a machine. Before they can begin to wonder why he was created they hear a voice and Bill Rizer's face appears below them. It turns out that Master Contra was just a puppet, and Project C was controlling everything. Project C explains that both he and the cloned Bill were part of a 10 year old projected designed to destroy all life on Earth as a means to end all war. The project was designed to recreate Bill, the ultimate soldier, in two forms. One was a clone, then other was a living weapon, which is Project C.
You have 30 seconds to destroy the four life support pods connected to Project C before he destroys you in an electrical blast (100%). If time runs out its game over, regardless of how many lives you have left.
As before, your ranking determines if the game ends or you move on to the next level:
- If your average ranking is a B or lower: The base is destroyed, presumably with you still on it. While the weapon is destroyed, Project C is not. Rendered powerless, he is left drifting in space.
- If your average ranking is an A or S: You will automatically start Stage 7.
