1. What does the starship sensors do? I'm aware there's a skill called that, but I thought i saw some science consoles that boost that particular stat, so I'm asking about the stat itself, not the skill.
2. What does the flow capacitor stat do?
3. What does the particle generator stat do?
4. When you buy the Cathian race, are their traits available for use on custom alien races? Or is it strictly for Cathians?
1-3: Right klick the consoles and read the "info", this should give you a basic understanding.
4: The trait pools are fixed. Unlocking another race won't give access to more traits or customizing options for aliens.
