Currently under development, Hollow Knight is the first game by Team Cherry, an indie games team comprised of 3 people based in South Australia.

Hollow Knight is a challenging, beautiful action adventure game set in the vast, inter-connected underground kingdom of Hallownest. A 2D action game with an emphasis on skill and exploration, Hollow Knight has you fighting a fearsome host of deadly creatures, avoiding intricate traps and solving ancient mysteries as you make your own way through fungal wastes, forests of bone, and ruined underground cities.

The atmosphere is eerie and sometimes unnerving, but there is a good-hearted core of humor and levity in there too, especially when conversing with all of the weird and wonderful NPCs you’ll find along the way. Hollow Knight has beautiful traditional art, fluid and responsive action, challenging but fair game play and a bizarre insect world begging to be explored and conquered.
