Stage B1 is the 14th Stage and the 1st bonus Stage of Sky Force Reloaded.
Key Notes[]
- All three Bonus Stages have a massive difficulty spike, even on Normal Difficulty.
- There is a total of 1160 stars in this level (on Normal difficulty).
- There are piles of barrels at the start of the Stage which, when shot down, launch one barrel in the air, then the barrel explodes, damaging you if you are close nearby (their damages are laughable, but capable of ruining your "Stay Untouched" runs).
- There are fast Dune Buggies that appear at the start of the Stage, whose destruction is required for 100% destruction. Comparing to the version seen in Stage 1 and Stage 3, they are much stronger here.
- There are Railgun Tanks at the start of the Stage that even if their turrets are destroyed, they will still be able to escape unlike most Battle Tanks.
- At the start of the Stage and somewhere in between, there are indestructible doors that will instantly destroy your Plane if collided with.
- There are indestructible Sawblade Drones which can quickly rip your Plane apart. On mobile, releasing the finger controlling the Plane to slow down time will give more time to react to them.
- There are static lasers in the air which act like a wall to constrain your maneuvers. They can deal massive damage and even knock down Energy Shields.
- All the railguns here (even the ordinary) are red in color.
- There are some SAM Turrets and twin AA Cannons on the walls that only have a limited angle and cannot properly aim at the player directly (but they will still shoot).
- There are harmless Spiderbots on the walls that are similar to APC Tanks on Stage 12, required for 100% destruction despite that fact.

Survivors[]
Stage B1 has 22 survivors, the highest number in the game. Below are their locations in order:
| Description | Location |
|---|---|
| 1st survivor: located at the very start of the Stage on the right side of the screen between two metal towers, near a pile of burning oil barrels. A Railgun Tank will appear on the far left. | 
|
| 2nd survivor: located on the right side of the screen, to the left of another metal tower. Two Railgun Tanks will appear nearby. | 
|
| 3rd survivor: located in the center of the screen on a thin walkway, which leads toward the base that most of the Stage takes place in. | 
|
| 4th survivor: located on a joint of one of the left arms that help open the doors of the base. The survivor moves in a curved motion as the door opens, eventually ending up on the far left side of the screen. | 
|
| 5th survivor: can be seen once the interior is revealed. Located in the middle of the screen on a small platform, in front of a wall of laser segments and an Energized Spider Railgun. | 
|
| 6th survivor: located on the far right side of the screen, sharing the same platform with the second Dual Railgun Turret. | 
|
| 7th survivor: located on a platform on the right side of the screen, in front of a wall of lasers. The first two twin AA Cannons can be seen shortly after. | 
|
| 8th survivor: located on a low platform running down the center of the screen, in the middle of the first four twin AA Cannons. | 
|
| 9th survivor: located in the middle of the screen on a lower bridge suspended above a deep hole with pipes running down into it. A large number of Drones will fly out of the hole to the left of the survivor. | 
|
| 10th and 11th survivors: located on opposite sides of the screen, on two separate pipes that run across the screen. There are two Supercharged Mantis Cannon Turrets ahead waiting to ambush. | 
|
| 12th survivor: located in the middle of the screen on the tall platform and between two red Radial Cannons. The platform also houses two Supercharged Mantis Cannon Turrets and a type II Laser Turret. | 
|
| 13th, 14th and 15th survivors: located on two separate bridges; the first survivor stands alone on the bridge in front that connect two SAM Turrets together, while the remaining two stand as a group on the bridge behind. The area is showered with bullets discharged by three Drone Fighters. | 
|
| 16th and 17th survivors: after encountering two type III Laser Turrets, they can be seen as a group on an extended platform on the left side, near the tip of a large ballistic missile, | 
|
| 18th and 19th survivors: located near the end of the same missile on separate platforms on opposite sides of it. | 
|
| 20th, 21st and 22nd survivors: the first two can be seen as a group on the right side, standing on the end of a platform that also houses two type III Laser Turrets. The remaining one stands on the left side of one of the pipes. Try to rescue the final one before the Quattropus boss appears, as its dangerous swinging arms will make it risky to stay still and rescue. |

Dispensers Locations[]
Stage B1 only has one mysterious dispenser.
The mysterious dispenser is on the left of this metal platform, which it shares with two Laser Turrets, an antenna and two survivors.
