Scenario Files

Files with the .Scenario extension are used by the game to load scenario/campaign data for starting up a map.

### Scenario File locations - SRU

.Scenario files are found in the following places;

* /Campaign
	+ These are the Campaigns
* /Scenario
	+ These are the Scenarios
	+ There are sub-folders for scenarios of different eras (SR1936, SRCW, etc)
	+ /Scenario/Custom - folder for Custom games
	+ /Scenario/Workshop - Added in March2020 Update - Folder to assemble & upload Steam Workshop MAPS sandboxes.
* /Multiplayer
	+ No Longer used effective April 2020 Update - Multiplayer now uses the Sandbox Folder
* /Sandbox
	+ These are the Sandboxes used for Single Player and Multiplayer
* /Common
	+ New in April 2020 Update
	+ Used to store files that are used for multiple scenario/sandbox/campaigns etc
* /Tutorial
	+ These are the Tutorial Scenarios

### Scenario Support File Locations - SRU (April 2020 Update)

Starting with SRU Versions after 9.1.302, the game engine supports a file structure inside each scenario file location. The folder of the support files must be the same as the name of the .scenario file

*For example: MyGame.scenario in the /Scenario/Custom folder:*

* */Scenario/Custom/MyGame/ is the folder to hold support files*
* */Scenario/Custom/MyGame/MAPS/ would be looked at first for loading files from the MAPS folder, this would override anything in the core game or a workshop mod.*
* *Any files unique to each scenaro/sandbox/etc should now be stored under this scenario folder, and not with the core game games.*

Note that even though this system also allows over-riding game engine files such as graphics, UI, etc, there are issues with such usage. At present, this file structure should be used only for items related to cache building. For other game engine items such as graphics, a Steam Workshop MODS item should be used instead.

### Scenario File locations - SR2020

.Scenario files are found in the following places;

* /Campaign
	+ These are the Campaigns for Supreme Ruler 2020
* /Scenario
	+ These are the Scenarios for Supreme Ruler 2020
* /Multiplayer
	+ These are the Multiplayer Scenarios for Supreme Ruler 2020
* /CampaignGC
	+ These are the Campaigns for Global Crisis
* /ScenarioGC
	+ These are the Scenarios for Global Crisis
* /MultiplayerGC
	+ These are the Multiplayer Scenarios for Global Crisis
* /Custom
	+ These are the Custom Scenarios for Global Crisis. Modded files usually go here.

### Scenario File Data

.Scenario files contain links to various files used to assemble the cache file and tell the game what cache file to use. When a cache file is not found the game will create a new cache.

The command #include (common in C++) is used for the files that are linked in.

The data in the .Scenario file is divided into 3 sections:

* Pre-Cache Data
* Post Cache Data
* Lobby settings

Post Cache Data

Some information is applied to the cache file after creation. This data can be changed without requiring a rebuild of the cache. Some of the pre-cache data files can also be included here but this will increase load times. The .OOB file in particular should not be here unless it is a small custom .OOB.

The following files are usually in the Post Cache Data:

* Region briefs and e-mails (usally LocalText-RegionsGC.csv)
* Scenario specific briefs/e-mails (usually [scenarioname]-Text.csv)

The following data types can be added to the end of the .SCENARIO file:

* &&UNITS data (usually from DEFAULT.UNIT)
* &&CVO data (regional data overrides)

### Lobby settings

These are the default settings for game variables and setup options. Players will be able to adjust these in the lobby where the option exists.

The section starting with the header "**&&GMC**" usually contains the following data:

Setup / Options:

*Note that Setup/Options for Campaign .scenario files are ignored, instead all defaults/initial values are loaded from the special CLOBBY.Scenario file instead.*

### Scenario File Overrides

At the bottom of the file it is possible to add regional data formatted as found in the .CVP file to change existing values.

For example, by adding:

```
&&CVP 1106
techlevel 104

```

Region 1106 (Poland) would be given a tech level of 104
