There are a lot of bullet hell shooters on the horizon. Not all of them are coming to the States. Gundemonium Collection, a localized bundle of three indie developed shooters, will be available for PCs on May 18, 2010.
Gundemonium Collection has three games: Gundemonium ReCollection, GundeadliGne, and Hitogata Hapa from Platine Dispositif. Out of the three I’m only familiar with Gundemonium ReCollection, a horizontal shooter remake with a neat progressive difficulty. See the “phase level” bar in the top right? When you overheat your gun from firing too much the game gets tougher. Use a bomb to clear the screen and the phase level goes down making the game easier. However, less things to shoot means less possible points to earn.
For $19.99 you get three games with Windows 7 support and fanservice in the form of creator interviews.
Here are more screenshots of Gundemonium ReCollection. Pictures of GundeadliGne and Hitogata Hapa are on Rockin’ Android’s page.
