Akaneiro: Demon Hunters, BigHead BASH, and Crazy Fairies, revealed its next project is a collectible card game/RTS set in the Underworld with the working title Hell Invaders.
Players can battle it out in a single player campaign or take up cards and fight in PVP arenas. For more peacefully inclined souls, trading, card management and other social features provide ways to enjoy eternal damnation.
Hell Invaders features actual card battles--rather than two cards "fighting" on a table, the creatures within the cards actually have 3D representations that fight it out--as well as cards that sport upgrades and swappable skills, so even cards for the same creature can be completely different.
Hell Invaders is currently scheduled for a Fall release and will be playable on PC, Mac, Linux, and tablets.
