Inferno was Paradise's first release.

You steer a craft around various maze-like levels putting out fires,
There are a variety of enemy craft and gun emplacements, and several different power-ups to collect, as well as lots of objects which just gain you more points. Some levels require you to collect keys to progress, and you are often working against a tight time-limit which can be extended by collecting suitable objects, this last action being the key to completing the level.
