Stage B3

Stage B3 is the 16th Stage and the 3rd bonus Stage, as well as the final Stage of Sky Force Reloaded.

Key Notes[]

All three Bonus Stages have a massive difficulty spike, even on Normal Difficulty. This Stage is especially tough, not only with many new Enemies and Obstacles to deal with, but also the Enemies have an enormous health pool which only gets worse on Nightmare.
There is a total of 1059 stars on this Stage (Normal difficulty).
Similar to Stage B1, the Stage features burning piles of barrels that launch an explosive barrel up to the Plane if destroyed, damaging it if nearby and potentially ruining Stay Untouched runs.
As the final Stage, B3 is a candidate for the hardest Stage in the game, housing many powerful enemies such as the Jet Fighters that rain many bullets down the screen, the type III Laser Turrets and Heavy Cannonball Turrets with the ability to destroy the Plane in a blink of an eye as well as many Hot Air Balloons that shoot accurate and high damaging homing missiles at fast rate. Many of them (and even the Lewiatan boss) even has projectiles that can penetrate Energy Shields.
The Triebflügel Plane enemies, which are exclusive to this Stage, potentially has the highest amount of hit points among all Prop Plane type enemies (against which maxed-out Wing Cannon projectiles can only pierce through one or two).

Stage B3 has a total of 16 survivors. Below are their locations in order:

Description	Location
1st and 2nd survivors: located at the very start of the Stage, each can be seen standing at the cut-off of two separate railways leading toward South and West.
3rd and 4th survivors: located on the big metal platform on the left side that houses the first two Heavy Cannonball Turrets. One stands between the two turrets while the other stands further back.
5th and 6th survivors: located on the top perimeter of the first metal building. One stands on the left side of the screen behind a Mega Bomb dispenser while the other stands on the right side and in front of a type III Laser Turret.
7th - 10th survivors: one of them stands alone on the far right side of the screen while the remaining three stands on another building to the left side, in a circle around a Laser Turret.
11th and 12th survivors: located on both ends of a bridge that connect the building said above to the next one on the left.
13th and 14th survivors: located as a group on the left side of the screen, on the same bridge with a mysterious dispenser and a Heavy Cannonball Turret. A fleet of Hot Air Balloons can be seen shortly after spotting them.
15th and 16th survivors: located as a group on the final bridge that initially connects with the Lewiatan boss. A second fleet of Balloons will pass over nearby.

Stage B3 has four dispensers: one for each type of power-ups and one mysterious dispenser for crate delivery.

The Stage background suggests the base is some kind of maintenance and production facility for weapons with the structures being based on the 20^th century or earlier (except type III Laser turrets). This is odd when comparing to the futuristic looks of Stage 13, B1 and B2.
There is, actually, no information on whom does this facility belong to. However, four Scarlett Mantis symbols on the Lewiatan boss suggest that it (or the whole base) used to be part of her army.
In the background, another zeppelin similar to Lewiatan can be seen under construction. A large gatling gun is also being moved around, but the Lewiatan boss doesn't have it as an armament.
On the 2006 version of Sky Force Reloaded, every type of Prop Planes would rarely shoot a bullet that travel straight downwards. However, only the Jet Fighters on this Stage shoot bullets in the current version.
