I've done pretty well with missile defenses while playing Endless Space so far. Getting killed by missiles? Put in more of best known flak module. Problem solved! But now I'm getting interested in making mods, and I've realized I don't really understand missile defenses very well.
1) Looking at the game's XML files, it looks like there are 4 rounds per phase; missiles fire in the first round then spend the remaining 3 rounds reloading. This means beams/kinetics fire 4 times per phase, though, and for some reason my memory is insisting that they only fire 3 times. Am I just crazy? I started playing during the alpha, did it used to be 3 rounds in a previous version?
2) I know defenses are per round, but how many rounds can missile defenses fire on missiles? Every round they're in flight or only the final round right before they hit?
3) What happens when incoming missiles have a higher evasion rating than my defense modules' interception rating? Do multiple defense modules tag team missiles? So if I had 3 flak modules, each with 5 interception rating, trying to counter 2 incoming missiles, both with 7 evasion rating, two flak modules would target the first missile and one would target the second missile, resulting in 1 missile shot down? I assume any extra interception rating the module(s) has/have beyond what's necessary to take down the missile is wasted.
