Open up your steam game library and on the left hand side right click on Frostpunk. A menu should appear, you'll want to click the last option titled "Properties" and a new window should open up.

In the new window, you'll want to go to the General tab, located on the top left hand side, and will want to type the phrase "-devconsole" in the text box at the bottom labelled "Launch options"

Simply launch Frostpunk and load up a game. This developer menu is the games console. When you load into the scenario you want to use this in, click the backtick key. Its location varies depending on the keyboard your using but generally it is below the esc key and above the tab key.

You should now see a red half transparent box on the top of your screen, with some text in it. Simply type in "ShowDebugButtonsPanel" and click enter. Check the FAQ page to see the other commands you can input here.

You should see eight boxes on the top left of your screen. Hovering over them reveals what their function is. The one labelled below is the cheat menu. Type 'HideDebugButtonsPanel' to hide the red box on your screen.

Will this remove my achievements and/or prevent me from getting achievements?
No, this method will not prevent you from getting achievements and it won't remove the achievements that you've already achieved on your save. Using this cheat menu will not change anything about your game save unless you want it to.

What are all the cheats this provides?
I'll split this list into the safe and unsafe cheats. Do note that while nobody has had their save corrupted by using unsafe cheats, it is still possible that this may occur.

Here are the safe cheats:
Instant construction, Instant research, Instant expedition travel, Unlock all technologies, Unlock all buildings, Unlock all sociotech, Resources boost, Display placement areas, Debug events, debug bars, enable time in frostland, display colliders, display selectors, display camera bounds, unhide sites

Here are the unsafe cheats:
Infinite resources, Freeze citizen statistics, immortal citizens, no critical citizen statistic levels, valid placement everywhere, unlock all unlocks, research all tech, research custom tech, change weather, reveal sites, decrease temperature*, increase temperature*

*Increasing/Decreasing temperature is done by 1 level at a time

Can I give myself a specific amount of a chosen resource?
Yes, simply open up the console in game (backtick) and type in
SetResource('ChosenResource', 'Amount').

Replace 'ChosenResource' with:

'Coal' for Coal
'Wood' for Wood
'Steel' for Steel
'Steam Cores' for Steam Cores
'Raw Food' for Raw Food
'Food Rations' for Food Rations
'Bodies' for Bodies (Organic Fertiliser Law)
'Wooden Materials' for Structural Profiles (Last Autumn + Builders Mode)
'Steam Tools' for Steam Exchangers (Last Autumn + Builders Mode)
'Steel Plates' for Steel Composites (Last Autumn + Builders Mode)

'Amount' is just the amount of the chosen resources you want.

Can I change what day it is?
Yes, type in SetGameTime('Day') in the console (backtick) and replace 'day' with the day that you want to set it to. You can use this to essentially skip storms at will.
