The slick graphics makes you actually feel like you are wading the streets of Berlin. Some excellent visuals throughout the playthrough. I only hit the single player as multiplayer seemed a little dead, so the run was a little short at three and a half hours, but I wasn't too fussed about that as Steam actually released this game for free for a day a couple of weeks back, so hopefully most people will have it already.
Story-wise, it is very much like a pre-cold war setting, so anyone who likes stories set in that era will certainly enjoy following the plot. I on the other hand, was more focused on the gameplay. Being able to snipe through hoards of enemies from your chosen hidden location is so satisfying, you can often take on ten or twenty enemies at the same time, you feel bad-ass by the end of it all.
If you haven't already got the game in your library from the free event a few weeks ago, this is certainly one you should be playing. Sadly it is still fairly expensive at £22,99 so you may be best waiting for it to go on sale
