Bomb Alley - Jason Charlesworth (Your Computer-May 84-Page 80)

JASON CHARLESWORTH WITH A HILL-HOPPING SPECTRUM GAME.

The aliens have been defeated thousands of times and have decided to now live
out in the open. Now the aliens are seeking revenge for their previous defeats
and have built a massive missile with which they intend to destroy earth. Your
mission is to fly past all their defence systems and destroy the missile.
 Your space ship is equipped with photon torpedoes - you can have five torpe-
does flying at anyone time - bombs and also a terrain mapping system. This
produces a samll picture of what the landscape is like - the left hand half -
and what the next section of landscape will be like - the right hand half.
Spread across the land are huts, radar posts, missiles, fuel dumps, fizzers
and asteroids.
 The game has four phases. In phase 1 there are lots of missiles and a few
huts etc. spread across the relatively flat land. If you shoot a fuel dump you
gain 50 fuel units, but if you run out of fuel, you will crash. Phase 2 gets
very hilly and to make it even more difficult there are asteroids which unfor-
tunately for you can not be shot down. Phase 3 is slightly less hilly than 
phase 2 and it is here you meet the fizzers, small animals which bounce up and
down to get in your way. Phase 4 is a mixture of phases 1-3 and hidden some-
where in phase 4 is the missile which you must destroy.
 The game features:
 A high score - To get on this you must destroy the missile. If you miss the
missile your game is over.
 A trainer mode - In this you have an infinite number of lives and so can die
as many times as you like. To get out of the trainer mode use the 0 key which
acts as an abort key.
 A demo mode - This shows all the terrain, to get out of demo mode use the
abort key.
 A speed change option - The speed of the game can be changed from 0 to 9 -
beginners speed. It starts off at speed 5.
 An information option - This prints out the values of all the objects you can
destroy.
 To set up the game type in listing 1 and save it on tape using SAVE "Bomb 
Alley" LINE 1. Now comes the difficult bit, typing in the machine code. Becau-
se of the data used in the game - 2K of data for the scenary and K of data 
for the characters - the program is long the machine code and data together
take 5.6K.
 The machine code is put in three programs, listings 2-4. First type in lis-
ting 2 and run it. If any error is found in the data the program will tell you
which line needs changing. When the data is all poked in correctly, save it
with
        SAVE "CODE1"CODE 30767,2000
Repeat this for listing 3 and listing 4 saveing them with
        SAVE "CODE2"CODE 30767,2000
and     SAVE "CODE3"CODE 30767,2000
respectively. Now rewind the cassette and type:
        CLEAR 27099:LOAD "CODE1"CODE 27100: LOAD "CODE2"CODE 29100:
        LOAD "CODE3"CODE 31100
 When this has finished loading all the code, save the whole block directly
after Bomb Alley with
        SAVE "CODE"CODE 27100,5667
The game is now ready to play. To play it rewind the cassette and type LOAD"".
