Looks like PC definitely is the platform to pick up Sniper Elite V2 if you haven't yet: developer Rebellion not only added an exclusive multiplayer mode to this version of the game, but is acting on its plans to continually flesh it out with more maps. Today you get the first two -- named Opernplatz and Black Market -- of what sounds like many free maps.
Besides new content, there is also performancce improvements for those experiencing issues, and a variety of tweaks and fixes. None are huge, but put together should provide a more smooth and enjoyable experience.
Hit the source for the full notes if you like, and boot Steam to get the patch.
