The 1990s PC game Syndicate is getting rebooted by Starbreeze Studios. From a top-down RTS-esque feel from the original PC game they’re changing it to an FPS.
This walkthrough shows about 11 minutes of gameplay, just about one whole mission. It should give you a feel for the tone of the game. Admittedly this mission looks pretty slow hopefully the pace will shift around through out the game.
Look for Syndicate in February 2012 for Playstation 3, Xbox 360, and PCs.
