River Raid
shoot'em up game for Commodore 64, 1984

------------------------------------------------------------------------------
Use Control Port 1 and 2.
You are a fighter pilot with an important but deadly mission:
You must destroy a number of vital enemy bridge links that are
well defended bt helicopter gun-ships, deadly land tanks,
ships and observation balloons.
You must fly down the river valley and destroy the bridges at
every opportunity.
A bonus jet is awarded every 10000 points scored.
Manoeuvre your way down the meandering river valley, avoiding
the cliffs on either side and destroying the enemy ships,
balloons, helicopters and tanks as you go.
Keep an eye on your fuel gauge and collect more fuel by
passing over the ´FUEL´ dumps. These are the only items in the
game that you are permitted to come in contact with.
You can score points by destroying enemy craft and fuel dumps,
and extra points are awarded if a bridge is destroyed whilst a
tank is crossing it.
Chocks away and good luck!
