Denarius

In Denarius, the Rignalian race is colonising the Solar System, placing chlorine pools in cities to support their life-forms. Pilot a space fighter across 16 infected cities, destroying or avoiding alien crafts while collecting as much chlorine as possible.

The game uses a constantly scrolling, top-view vertical-shooter format. Obstacles can cost one of your three lives, while a laser and one limited-use shield are available in each city. Chlorine pools appear as small squares in clusters, and the amount collected is converted into points at the end of the level.

Surviving a city leads to a bonus stage where gas walls move down the screen. Guide your fighter through the gaps in each wall to continue, using a joystick for control.
