This is impossible to happen with the current 0.88.1 Piratez ruleset since there are no Port Attack alienMissions listed on the ruleset.
Then it must be a carryover from 0.88 save, I apologize for this false alarm.
Should probably start a new game for playtesting purposes.
But I just spoiled a Star Gods retaliation mission by looking at save and I`m determined to have glorious death first.
edit: some 0.88 impressions
Love the Vulcan and 37mm Rifle - superheavy superpowerful stuff, really fun to use. Vulcan is first minigun style weapon in openXcom I ever considered using, it can punch even through walls in Hobbes terror terrains and that is just awesome. Although ROF should be higher, I think, (not in a shots per auto sense, but in a projectile speed sense, so unloading whole burst does not take so long) there should be a sweet spot, where you can appreciate the mayhem, SFX does not clip, and burst does not take that long.
And Loader suit looks just awesome. Goes well with Vulcan weight too. From the teaser images I thought it will be a new ultimate power armour, and was kinda dissapointed at first, but then got 2 Vulcan equipped Loaders and it turned out hella fun.
Not fond of new "Hidden movement" background, switched it to old one.
On the fence about new interrogation - imo that extra step isnt really needed. Was the old one broken? I thought it worked pretty well. overall it feels needlesly complcated and not fun, despite it being just a single extra step.
Looking forward to see new transport crafts and melee stuff.
