S.T.A.L.K.E.R. Online is a canceled multiplayer action role-playing game with an isometric camera view in the S.T.A.L.K.E.R. universe. The game was not made in 3D, but using isometric graphics. A custom engine was created for it, running using Adobe Flash. Development started in 2009, the concept of the game and many levels were worked out. A complete stop occurred in 2011, due to the “low priority of the project.”
