Sniper Elite 4 is an upcoming World War 2 shooter that's all about creatively dispatching whole boatloads of Nazis. You can use the titular sniper rifle in order to take them out from afar, use your trusty combat knife in order to remain stealthy, place a whole bunch of traps if you don't feel like doing all of the work yourself, or just go berserk by throwing around bombs and bullets like they're going out of fashion.
In order to demonstrate all of this madness in action the developers have just released the "Timing is Everything" launch trailer. There is zero actual gameplay on display, but if you're up for ridiculously over-the-top action then you're probably going to find it quite enjoyable. Have a look:
On the other hand, if you're looking for an actual gameplay video that shows off all of these features, you'll find it by going over here. The video covers pretty much everything from the story campaign to all of the different ways you can dispatch your foes, so if you're looking for a quick overview its definitely worth a shot.
As for Sniper Elite 4, it will be arriving this February 14th for the PC and consoles. If you would like to learn more I would recommend going to the official website for specific information, and Steam if you're just looking for a general overview and a couple of gameplay videos.
