Syndicate (2011)

Syndicate was a really niche entry into the Cyberpunk genre that flopped commercially but had some interesting ideas about corp-ocracy and the way businesses of the future would wage warfare against each other like nations used to.

That main menu music has echoed in my brain for years. Deus Ex: Human Revolution would have been first but Syndicate is less well known and I figured someone already mentioned DE:HR at some point here.
