These and other videos will give you an impression of how Steel Fury plays - first video mostly stock, the others illustrating kit and missions available with mods.
Steel Fury doesn't really give you much of sense of player persona or the unit you're serving with - the stock campaigns are decent, but fairly impersonal compared to PzC. The additional missions are mostly that - single missions. A few are tied together into campaigns. Some of these, like Schulze's Diary (first two screenshots below) and the movie based
Fury campaign (third screenshot), attempt to provide a more immersive approach.
