Deep in the mines of Zylon, a team of geologists are trapped. It is up to you to rescue these men in your specially adapted airship, but beware of the acid rain drops which cause you ever increasing damage.

Be careful as your airship will be destroyed after the damege point reduced. Damage is reduced by ten point each time a circle item collected – rescuing all geologists (24) successfully and returning to the surface completes one level of which there are eight in total.
