Tarnish is just my prototype for an FPS game. It has some multiplayer parts working: server database, registration, authentication. I am focusing on the core FPS aspects for a while. The parts that would work for most kinds of FPS games, so that I can change the direction of Tarnish in the future, or to develop separate FPS games with different focuses, but similar core mechanics. Tarnish potentially would be a multiplayer survival game. There may be zombies, or aliens, but trying to survive and thrive, be it with friends or solo, will be the main theme.
