FOXBAT [FIREFOX] (16K Spectrum)
by A Howes
from Popular Computing Weekly (24 February 1983), pages 8-9

Foxbat is a fast moving graphics game for the 48K Spectrum. The object of
the game is to fly your plane as low as possible over the mountainous
terrain which rolls across the screen. The lower you fly, the more points
you accumulate - but watch out for trees and steeply rising cliffs. My high
score is 2828, but I am sure it is possible to do better.

The mountains are moved across the screen by machine code. The height of the
mountains is controlled by the data stored in lines 1000-2000. The user
defined graphics for the planes and trees are contained in lines 2010-2020.

The In statement has been used instead of INKEY$ as this allows two keys to
be read at the same time.

The control keys are Z (left), X (right), P (up) and L (down).
