Synduality: Echo of Ada

You and an AI mech named Magus explore a dystopian landscape in the year 2222. A catastrophic toxic rain event known as the Tears of the New Moon has nearly wiped out the human race - the survivors fled to the underground city of Amasia. To survive, the player character known as the "Drifter" must sell AO crystals, which can only be harvested in the contaminated outside world. To travel, you ride in a vehicle called the "Cradle Coffin", which you can customize. The game will also have a unique PvP option where you can compete online against other players playing their own missions - you may come across them in search of valuable supplies.
