In the first Sniper Elite 4 gameplay trailer, developer Rebellion shows off the new kill cams, takedowns, stealth abilities, shooting, and a little bit of sniping. At the very end of the video, there’s a tease for the Target Führer campaign mission, which is available to everyone who pre-orders the game:

With many millions of views on YouTube and countless gameplay hours logged, the series’ renowned Hitler-assassinating bonus missions have been a fan-pleasing tradition since Sniper Elite V2.
In Target Führer, players will once again set their sights on history’s most notorious tyrant, in a forgotten corner of the Mediterranean where a secret Nazi U-boat facility threatens Allied shipping. When agent Karl Fairburne attempts to assassinate the base’s commander, he finds his target already dead, executed in person by a shadowy visitor. Karl’s mission has changed: Target Führer!
Players must destroy the imposing U-boat base and take down Hitler in as many ways as they can in this replayable campaign mission for 1-2 players.

Bundling together detailed camouflaged sleeves for the seven iconic WW2 rifles in Sniper Elite 4, the Camo Rifles Skin Pack is also included with pre-orders.
