*** PLAYING THE GAME ***

* Object *

How Far Can You Invade Our Scramble System?

The object of Scramble is to guide your ship through the five unique stages to the BASE stage and destroy the command center while avoiding 
or destroying numerous enemies, including rockets, generators, UFOs, and meteors!


* Player Control *

Use the joystick to guide your helicopter through the scrolling terrain.  

- One button joysticks:  Press the button to simultaneously fire a missile and bomb.
- Two button joysticks:  Press Button B to fire a missile and press Button C to drop a bomb.


* The Enemies *

- Rockets:              Launch straight up from the terrain towards your ship.  Be careful as some move twice as fast as others!
- Power generators:     Clutter the terrain making it difficult to navigate the narrow tunnels.  
- UFOs:                 Fly in a wave pattern making them difficult to destroy or avoid.
- Meteors:              Dodge the fast-moving meteors which cannot be destroyed.


* Fuel *

While flying across the terrain, your helicopter will expend fuel.  Keep an eye on the FUEL meter to make sure you don't run out!  
To get more fuel, destroy the fuel pods with your missiles and bombs.


* Stages *

Mountain stage:         Pilot your ship over the rocky terrain while avoiding incoming rockets and destroying ground target generators and collecting fuel.
Tunnel stage:           Avoid or destroy the swarming UFOs while destroying the ground targets and collecting fuel.
Meteor stage:           Dodge the indestructible fast-moving meteors!
City stage:             Fly over the futuristic cityscape, destroying the enemy installations and avoiding the rockets.
Maze stage:             Navigate your ship though the narrow and winding maze to reach the BASE.


* Base * 

After successfully navigating the Maze, you will enter the enemy base.  Maneuver your ship towards the control center and destroy it with a well-placed missile or bomb and quickly 
ascend to safety to escape and complete your mission! 


In the demo version, the game will repeat Level 1 once Level 2 is complete.  In the full version, there are 99 levels to complete.

GOOD LUCK!
