If you liked the Far cry 3, you'll probably like this one too. It has some new features like, you can drive a helicopter, you can pick up a body and drop it again, autodrive option etc. which is good but it lacks a story of its predecesor.

This is a survival game of ordinary people not soldiers. It's something refreshing in that sense but it can be hard on you mentally. But overall it's a very good game.

One of the best games I ever played. I invested 300 hours in this game already, and I have barely touched dlcs.
