The collection offers Tennen-sozai's arcade-styled shoot-'em-ups eXceed 2nd - Vampire REX and eXceed 3rd - Jade Penetrate Black Package, along with Hiranyon's HellSinker, Siter Skain's Kamui, and Astro Port's Armed Seven.
The package also includes 07th Expansion's visual novel Higurashi When They Cry and Hato Moa's pigeon dating sim Hatoful Boyfriend. No, that's not a typo, nor are you imagining things -- it's a dating sim in which players search for love at an all-pigeon academy. Admit it: You're curious.
All games are available as DRM-free downloads, and Tennen-sozai's games include keys redeemable at Steam.
