For a few years now, talk of Blizzard working on a mystery MMO, tentatively named Titan, have surfaced. Little else has been divulged other than Blizzard saying it's a whole new IP. Well now it seems Blizzard's definition of "new IP" may differ from ours, or at least mine. Information has leaked that the new Titan MMO is actually an alternate universe combining all of the company's current IPs. Titan will merge the worlds of Diablo, Warcraft, and StarCraft in this alternate universe. Chris Metzen, Vice President of Creative Development, said that he's a huge fan of the Alien and Predator franchises and said Titan was inspired by the Aliens vs. Predator crossover. With three franchises instead of two, it was a difficult project to undertake, but he knew his creative team could come up with something fans of all the series would fall in love with.
Exact details have not been unveiled yet, but apparently Titan refers to the supreme god of the Xel'naga. For those familiar with the StarCraft universe, you probably remember the Xel'naga as the ancient, cosmic race that created the Protoss and Zerg, but was ultimately destroyed by the latter. Titan was apparently not only responsible for the creation of the Xel'naga, but also the Old Gods in Warcraft lore and Tathamet, the Prime Evil in Diablo lore.
Sounds like it should be a rather interesting world. I can't wait to see what the playable classes will be!
