In this side-scrolling game - scrolling from right to left - you fly a helicopter
through three different stages. In the first, you shoot enemy helicopters and aircraft
and avoid missiles as they speed towards you.
In the second, you can't shoot back, but the enemy balloons and airships don't shoot
either. It's just a case of avoiding them.
In the third, you arrive at the enemy base. You have to hit the controls at the end of
the ventilator shafts. When this is done, a slit appears on the barrier which you shoot
to destroy the base completely. Two indestructible helicopters guard the shafts. In
between these stages, you refuel by guiding your chopper's refuelling pipe. When the three
stages are completed, they are repeated at a faster rate.
The graphics are superb. The characters are incredibly well defined and sound is used to
good effect. All the expected options are here and, overall, this is an addictive shoot-'em-up
with some of the best graphics around.
