Early history

Independently apart from any other development team at Nimble Neuron, we formed a small group of developers to create a different kind of game. We had a vision of an online survival pvp game, where only one can survive from among 15 ~ 20 players to win the game. It’s not just another battle royale game – which, of course, are each excellent in their own way. We didn’t want to create one that needs intense physical engagements and abilities. We also didn’t want to create a game that’s the exactly a MOBA or MOBA-like battle royale — our focus was to convey the essence of fun taken from the MOBA genre and the thrill of planning/ executing character growth strategies while interacting with many environmental factors. A project was born — a ‘survival game’ with the importance on planning/ operating ‘character growth strategies’ like searching for and crafting items, gaining mastery and getting stronger based on the players choices, all on a beautiful atmospheric 3D battle map. Pursuing and keeping this initial mission in mind, we will upgrade the quality of gameplay and aesthetics for players to enjoy a different style of 3D survival pvp game.
