This mod is actually incredible, the models and art style look beautifully like a more technologically advanced taiidani republic that'd be around in the HW2 era. An empire the size and age of the taiidan doesn't just go away and get instantly replaced by gigantic Vaygr hordes, the Republic would absolutely still be around after the events of cataclysm and as far as i'm concerned, this is canon for what they'd be up to.

Am keen to see where the mod goes from here! The campaign missions so far are extremely well done too, the city of petra looks super cool and I love the way it's defence systems work and the mystery of why the garrison just bailed on it.

My main suggestion would be maybe having the escort mission take place before the prologue cutscene to establish what the Carrier group was doing prior to the campaign starting. This'd probably mean adding the Carrier in somehow, maybe by replacing one of the AI controlled republic convoy with a republic carrier that you can dock with? The escort mission as it is, is really interesting and narratively driven, it'd make a great opening to the campaign to introduce the faction, and the early missions where only strike craft are available will make more sense, since the carrier is just on minor escort duty and doesn't need the big guns.
