Crikey, from being an unknown (and yet somehow inevitably always an FPS) project of rumour and vapour, there's already footage of Syndicate to coo at/smash up your house in rage because of. Ten minutes of it! Which you can watch below.
Your perception is augmented with ambient information from the databurst. Like, duh.
It's rather strange hearing the rather bored narration over the top of such extraordinarily brutal violence, eh? There's quite a lot going on here. Hopefully we'll get our fingers on a copy of the game very soon, and report much more.
