Eidos has announced a "slew of assets" (including in-game augmentations) for those that "Like" DX: HR on Facebook. Since I rather agree with Rock, Paper, Shotgun's distaste for this sort of thing, I'm going to link via their article on the topic. A quote from Eidos:
More information.“Deus Ex has one of the most passionate, vocal and dedicated communities in all of video games, so offering a program that rewards that loyalty — even before the game is released — is a great way for us to give something back. The Facebook community now has significant control over the release schedule for some of our favorite assets. We have a ton of surprises and unlockables planned, so fans should invite their friends to ‘Like’ the page and start collecting these rewards.”
