You play Kim Kimberley, secret agent extraordinary.
Your mission: to safeguard the interstar transport, Snowball 9, as a last resort following catastrophic accident or sabotage.
Thus when your modified freezer-coffin wakes you with the Snowball still in transit, you know that something must be very wrong. You're weakened and disorientated from lengthy hibernation, but the fate of two million passengers is in your hands!
When the game was released, it was touted as having more than 7,000 locations. In reality, the game size is more akin to Level 9's comtemporary releases (~200 locations), with the remaining locations being a colour-code maze of otherwise idential rooms.
