Imagine A world, where all the myths and conspiracy theories are true. In where you Could be battling Mummies in Egypt with a gun one minute, And Fighting hell demons with a mythical sword the next. Where werewolves and vampires stalk the Transylvania mountains, and ghosts haunt hallowed halls. This, Is the Secret World.
There are 3 factions that are in play that all have different theories and religious views
Illuminati- A lot of science and guns involved here, Dont know much need to watch more dev diaries.
Dragons- A Chinese gang, Mostly the mythical side to things, Swords and such.
Templars- Not the baddies in AC, These guys stand to eradicate the Demons and such.
So basicly Its a modern day Mmo with a dark setting made by EA/Funcom. Watch the dev diaries, Its really cool.
