Are there UFO interceptors and alien bases defenses standalone mods?

[fireburn256]

Is nice.

Recently I have been trying out TWoTS and Hybrid Mod, and liked when UFOs intercepted my craft. And, well, the alien base defense mechanism when they spawn an intercept ufo to give my craft a nice and proppa welcome. So the question is as it is in the title - are there standalone such mods? So that I can enjoy it for closer to vanilla experience.

I know Hobbes did something like that, but the descriptions on openxcom.io are, well, too word-skimpy. The descroptions here on forum are a tad better, but still.

Thanks in advance and sorry if wrong place.

I am not aware of such a standalone mod (which doesn't mean that there aren't any), but the feature is present in most big mods in some way.

Hobbes made one when the feature came out. I don't think it has been updated recently, and is likely pretty bare-bones, but it should apply straight into vanilla.

(I have not used this mod.)

I checked. That mod only adds the ability for UFOs to be Killer Hunters, but the alien bases do not have the ability to launch UFO interceptors for their protection.

Correct. I do not know of any mods for that other effect.

I haven't done any modding, but looking at TWoTS for example, the respective ruleset adding base-defending hunter killers appears to be very simple, most of it caused by making the HKs more difficult as the months pass by:

    baseDetectionRange: 600
    baseDetectionChance: 45
    huntMissionMaxFrequency: 1440
    huntMissionWeights:
      0: #because no 'firstmonth' can be applied
        STR_ALIEN_INTERCEPTION: 100
      7:
        STR_ALIEN_INTERCEPTION: 100
      10:
        STR_ALIEN_INTERCEPTION: 90
        STR_ALIEN_INTERCEPTION_LATE: 10
      14:
        STR_ALIEN_INTERCEPTION: 30
        STR_ALIEN_INTERCEPTION_LATE: 70

.. and for example STR_ALIEN_INTERCEPTION is:

 - type: STR_ALIEN_INTERCEPTION
    operationType: 6
    raceWeights:
      0:
          STR_AQUATOID: 25
          STR_GILLMAN: 30
          STR_NAGA: 25
          STR_CARCHARODON: 20
(... omitted some for brevity )
    waves:
      - ufo: STR_FIGHTER
        count: 1
        trajectory: P1
        timer: 0
        hunterKillerPercentage: 100
        huntMode: 0  #prefer interceptors
        huntBehavior: 1


I suspect adding base defending hunter killers would be a very easy mod, perhaps only a couple of dozen of lines, if you leverage existing missions and ufos to the max. Maybe you could even try to create such a mod yourself.

Alien Hives mod uses interception alien missions for xcom1, with less variety and quickly upgraded (0: Large Scout, 1: Terror Ship, 3: Battleship).
