Laws of War was something that I really didn't expect Bohemia to run with, but I think it might actually be the best campaign they've done in the series and is a serious attempt at telling a war-related story. It's a story told from the unseen perspective never shown in any aspect of the games, it doesn't have any large-scale battles or much fighting at all. What is here is a moral question left up to the player which they make up from the campaign itself or the original ARMA 3 campaign.
It's not a big campaign by any means and it's not spectacular and it doesn't have any preaching to the player about what's wrong. Merely the player making the choices and the reaction from the aid workers and reporter, and it works well. Good attempt by Bohemia here to step up their game.
