Alien Configs

To edit alien configs in OpenCAGE, navigate to Edit > Configurations > Characters > Alien Configs.

From here you will be presented with a variety of options which relate to the selected alien config in the dropdown at the top of the window.

Read on to see a list of available properties with information about each.

By default, the alien runs the 'MODERATE' config. This is can be changed at runtime through the script entity NPC_AlienConfig by providing the appropriate config name.

Note that a lot of these values are additionally increased/decreased by the current game difficulty config.
