In Dark Spirits players fly with four familiars. Each of these spirits is powered by souls and can develop individually. Like other titles in Genterprise’s G.G. series, Dark Spirits is a 200 DSiWare ($2) game.
After Dark Spirits, Genterprise has a DSiWare tank game called D-Tank slated for January 14, 2010. Prior to these, Genterprise released two other DSiWare shmups Z-one and the Alice & Wonderland themed game, Wonder Land. So far, none of these games have been released internationally.
