DEATH DUEL (16K ZX81)

By special request, all the way from Yugoslavia, Tavcar Igor's Death Duel.

Death Duel is a version for the 16K ZX-81 of the highly successful Spectrum
game published last April. Written in machine code it improves on the
Spectrum game by giving a choice of speed and acceleration.

Two people play at the same time. The players race around the screen
leaving a trail behind them. Your object is to drive your opponent to crash
either into your trail or his own. Steer clear of the border - that's fatal.

Before battle commences you can change the speed and acceleration and set
the background character for the playing area. During play press T to
freeze the action and B to return to BASIC. Pressing Y will turn the
acceleration on; N will turn it off. The border character shows which
option has been chosen.

Use the following keys to steer:

Left Player  Right Player
1 - Up       0   - Up
Q - Down     P   - Down
D - Right    N/L - Right
A - Left     K   - Left
