Man, imagine if the assassins creed franchise was actually about assassination. Sigh.
Syndicate has a few assassination missions that almost rival Hitman's. They are now large sandboxes in large open spaces with lots of NPCs of different factions (that fight each other), and unique opportunities for infiltration/information gathering/special kills.
Syndicate is a legit fucking good assassination and stealth game (as well as a legit good game overall). The sandbox is amazing and it's actually fun even when shit gets fucked (unlike the earlier games which were barely ever fun at all).
One cool example: Syndicate has an innovative mechanic called 'Kidnap'. If you can get up behind an enemy while they are unaware, you can press the 'pick up' button to grab them and hold a blade to their back. You can then force them to walk with you - creating a small 'safe zone' around you that grows if you move faster and shrinks if you're slower. This lets you walk straight into 'Restricted' areas and straight past any other guards - providing you don't get too close.
It's an incredible mechanic, and one which would feel at home in Hitman. It's really smooth and intuitive and has led to loads of amazing tense stealth moments for me in Syndicate. Walking five feet away from a huge line of British police, into a building, up stairs past loads of other police rummaging in a house, before slitting my kidnapee's throat on the top floor, burning some documents, and leaping out the window.
Anyway. Syndicate is great. Enough of a derail.
I think I'll go in on Hitman after payday. Sounds right up my street. Funnily enough, Hitman: Codename 47 was the second PC game I ever bought.
