Order

Order
Order is currently one of the two purpose trees available, with the next one being Faith. Order is characterised by its militant style, with guards, large towers and loudspeakers. Its main aim is productivity and obedience, as opposed to Faith's spirituality and good intent. The order flag is a black, gear-like symbol on a red canvas.

Foreman
Order has quite a few advantages when compared to Faith, first and foremost the Foreman ability. This ability costs 10 Food Rations and in return boosts the chosen workplace's efficiency by 40 %. It affects automatons, too, and as unrealistic as that may sound, it is a major boon to any resource production, as the Automaton will be able to use the full 24 hour effect of this ability.

Discontent management
Order provides the player with easy and intuitive discontent management through the use of Patrols and Prisons. Faith, on the other hand, is more suitable for dealing with low Hope, so it is advisable to choose Faith if you are struggling with this, as Order has only one building for serious Hope management, which is the Propaganda Centre. However, the power of Order's discontent reduction capabilities gives the player more headroom for ie. Emergency Shift usage.

No Houses of Healing/Field Kitchens
Field Kitchens and Houses of Healing are the two reasons why most of the Frostpunk playerbase deems Faith stronger. Houses of Healing allow for Workers to cure people AND the Gravely Ill, which makes it a life saver if the City is low on Engineers. The Field Kitchen on the other hand prevents sickness, as it has the amazing ability to heat up nearby workplaces by one heat level up using five Food Rations per day. These buildings are very powerful and choosing Order will leave you without the ability to use them.

Worse Law layout
Generally speaking, Faith has better Law layouts when compared to Order. To get the essential laws for every tree, you will need to sign 6 laws on Faith, and 8 on Order. Of course, the neccesity of each law may vary from player to player, but Faith has crucial laws easily accessible from the start, which can't be said about Order in the same way.

Worse Hope management
The only real Hope management building for Order is the Propaganda Centre, which not only prevents the player from getting the golden path(atestation pending), but also remains inaccessible until later on in the game, while Faith has the Temple and the Houses of Prayer, which almost nullify any Hope loss.

The New Order
The New Order, similarly to New Faith, is the final law of Order. Roughly 10-40 people will die when you sign it, and Hope will be replaced by Obedience. Obedience remains at a 100 % at all times, and the only way to get yourself deruled is by raising the Discontent too much. Luckily for you, there is a new bulding erected automatically when the law is signed. The Execution Platform is a building that lets you quite literally fry and freeze a "Public Enemy" randomly picked from your male adult populace, and lower Discontent by a substantial margin. This allows for virtually limitless cruelty, as any rebellion will be quenched by a single execution. Signing this law should be a last resort for most players though, as it makes your ending bad instantly.

Trivia

 * The Execution platform kills people in a very cheap and efficient way by using scalding steam to burn and wetten up the victim, then the victim freezes to death if he endured the previous burns.
