This level also marks the reappearance of Buggers, who appear much smaller here. The main enemies in this level are skeleton-like soldier aliens, possibly those are skeletons of soldiers who were killed by the Red Falcon. The 7th level is a continuation to the alien base, it's made up mostly of dead alien eggs. After passing multiple difficult corridors, you have to battle a mini-boss, and then take out Gava himself.

This is the last time you see the default soldiers either. Instead of fighting the usual soldiers, you battle spider-like aliens. Here, the boss battled is an alien mothership shooting skulls and small bugs at you. This one you have to climb up too, there are some military complexes by the end.

After defeating the boss of this area, a machine shooting multiple laser beams, you can go to the mountain area, the fifth zone. Later on, the next level is a green in color high-tech base, which you need to climb up. The third level is a jungle level, reminiscent of the first level of Contra, though later on it changes into an earthquake possessed area (with a wall that comes out of an earthquake as the boss). Only the top driver needs to be taken out in order to go further though). The levels on this port are an abandoned city complex (with an Army Helicopter as the boss), standing before Fort Firestorm, that appears as the second level (boss - tank with three drivers. The original arcade version features less levels, and the game ends with a final fight against Emperor Demon Gava. Bill and Lance must not only fight against their former comrades-in-arms, but also a new mutated form of the same alien creatures they fought during their previous mission. This time, the alien forces have taken over an allied military base somewhere in Africa, possessing most of its troops. A year after the battle with the Red Falcon organization, Bill and Lance are sent on another mission.
