Stages
Stage 1 「VALLEY」

The assault
begins on the Federation’s secret factory, constructed in an ore mining region.
The Wayne brothers know this place well, as they themselves also carried on
certain design and project work here.
The boss, 「MD-113 Nose Lavagghin」, is now a somewhat technologically outdated
model. However, the offensive power of its large-scale
guns, which also lend stability to the craft, are not to be underestimated.
Stage 2 「PLATEAU」

An alpine town surrounded by beautiful lakes and forests.
But the Federation’s attack has reduced even this place to a state of
devastation.
The boss, 「SF-4518 Mad
Ball」 hovers in the sky
through 14 inverted propellers, and when it reaches its destination, it deploys
an excavation drill equipped on its underside and anchors itself into the
ground. It then can fulfill the role of a provisional stronghold at that
location.
Stage 3 「FACTORY」

Heading deep inside the Federation’s heavy arms factory
production line, the brothers now aim to destroy the experimental heavy bomber 「Slayer」.
Although still under production, part of its weapons are
operational, and a difficult battle can be expected.
The boss 「ST-22 Earth Crisis」 is an ultra-heavy tank equipped with 2 giant,
rapid-firing rocket launchers. Due to its massive size, it is too large to act
as a traditional tank and instead can only be utilized as a mobile fortress;
accordingly, only two prototypes were produced. Depending on the location of
its deployment, however, it can likely still fulfill a valuable role.
Stage 4 「PLANT」

The ruins of a maritime production plant located in the
northern part of the continent. Although the plant itself is already a ruin,
the Federation has repurposed it as a front-line base, deploying ground-based
forces all over.
The boss 「PS-50 Satanic
Surfer」 is a large, armored hovertank, originally designed to serve as a smooth
transitional element between sea and ground operations, greatly aiding in
landfall tactics. However, its armor and power requirements were not well
balanced, and it turned out to be unreliable for non-marine operations.
Stage 5 「CLOUD」

High in the clouds lightning flashes all around, and the
brothers chance upon the strategic heavy bomber Slayer leading an aerial
armada. The stormy weather limits combat visibility, lending a decisive
advantage to smaller ships, and perhaps a battle between the brothers and the
vastly larger aircrafts will now be evenly matched.
The boss 「G-616 Black
Heart」 was built by the
Federation based on the Wayne brothers’ notes. It is the Federations’ strongest
positional defensive fighter plane. Its fully mobile 35 mm machineguns are only
the beginning of its expansive arsenal; the ultimate secret of its power lies
in the miniaturized rocket engine. Although it takes 20 minutes to become
operational, its overwhelming heat obliterates its enemies
right out of existence.
Stage 6 「BASE」

Slipping
through the enemies’ main forces, the brothers infiltrate the base which serves
as the center of the Federation’s military operations. The interior is defended
not only by gigantic cannons, but also by innumerable tanks, making it an
impregnable fortress.
The boss 「DT-38A Junky Monkey」
was originally developed to serve as a machine for the construction and
handling of land mines. However, due the state of war it has been retrofitted
to construct simple gun batteries and serve as a positional defense if needed.
Stage 7 「AIR PORT」

The brothers now pursue the extra-large escape vessel 「King Crimson」 which has begun take-off from a secret runway. While in
pursuit, they engage in a dogfight with 「Black
Heart 2」, the newest model
fighter that has only just been finished. Defeating it, they pursue the
emergency escape unit ejected from King Crimson...
The boss is 「DT-070 Glow Squid」. King Crimson is equipped with a double and triple
failsafe escape plan for its passengers in the form of a cockpit unit which can
eject and fight on its own. The unit is called Glow Squid, and it too has its
own yet-smaller emergency escape unit built-in.
