These are the basic configuration options that most games will need to tweak for their theme/setting.
The default gear lists are designed for a Battlestar setting. If you’re using another setting, you’ll probably need to tweak the gear lists. If you have custom vehicles or unusual combatant types (like six-legged aliens.html), you’ll need to adjust the hit location tables.
These are advanced customization settings that most games won’t need to alter.
If you want to add more actions to the combat system, you should see the FS3 Roadmap tutorial for behind-the-scenes info about how the combat system works and how to add to it.
