New Industries and Cargos for OpenTTD
FIRS is available from the content service in OpenTTD, as a zip for manual installation, or as a source checkout for compiling locally (requires mercurial and various python dependencies).
A few things to know before setting up a FIRS game...
To avoid conflicts that could break your game, FIRS will disable itself if certain other newgrfs are detected in the current game. You'll see a message if this happens.
Conflicting newgrfs include other industry sets, such as ECS and PBI.
Many FIRS cargos are not transportable using the default vehicles. Fortunately there are lots of great NewGRF vehicle sets with FIRS support.
The in-game content service is a good place to find these.
FIRS has a number of parameters for gameplay behaviour. These cover things like economy choice, industry closure and station ratings. Parameters include help text explaining how they work.
Tip: parameters need to be set before starting a game. Parameters cannot be changed during a game.
You can jump right into FIRS gameplay.
