Scramble is the classic horizontal
Space-Shooter from Konami.
The Player controls a ship that must infiltrate the five levels of the
Scramble system and destroy the Base in the sixth. The first level has the
player over a decidedly hilly terrain. Player must dodge or destroy enemy
missiles shot from the ground. The second level is inside a cavern. The quarters
are not tight, but the swarms of enemy saucers make maneuvering difficult at
best. The player exits the cavern and is assaulted by a storm of fireballs in
the third level. The fireballs are fast and indestructible and must be manically
dodged. The fourth, or City level flies the player over a large metropolis.
Missiles fired at the player from the tops of buildings again become a threat.
The fifth level sends the player into obnoxiously tight machine tunnels. Pilot
error is the only (though formidable) enemy. The final level has the player make
an attack run on the Base, defended only by its position in a deep valley.
Gameplay is further complicated by the player's ship's consumption of fuel.
If the player's ship runs out, it crashes into the ground below. Fuel is
replenished by the destruction of the fuel tanks that liberally dot the ground
during the levels.
