What it was
The internal codename for Blizzard Entertainment's unreleased next-generation massively multiplayer game.
Titan was developed by a large team as a class-based science-fiction MMO set on a future Earth. It reached internal playable form but was never officially unveiled as a product or opened to the public; most detail comes from later interviews and reporting.

Why it ended

What it left behind
