Agartha (Dreamcast) Demo

Agartha is an Adventure game, developed by No Cliche and published by Sega, which was cancelled before it was released.
A playable demo (from E3 2000) leaked onto the internet in 2018. It shows the main character, a bearded adventurer, exploring a snowbound Romanian village. The gameplay, though still in a rough formative state, is like a cross between Resident Evil and D2.
