It's years after the release, but I've also started a (commentated) playthrough of the mod:

I didn't end up getting a lot of mileage out of either the Armored Exie option (too many Alpha enemy attacks deal 2+ damage so 1 HP and 1 armor doesn't do much), or the +1 damage option for the Photon Foil since a lot of other weapons can either hit multiple targets or get more efficient damage upgrades if you want single-target damage.
Still, the squad worked together very well and the Hoagall + Exies are a very powerful counterpart to the vanilla game's Light Tanks. Hoagall's low move balances this out a little bit but throwing in free chasm tiles on top of that makes it a pretty powerful mech - which does really justify that 4 core cost for fire, it's strong enough even without it but becomes ludicrously powerful once the fire is online.
Very fun to play on Hard mode, and I think this squad would have reasonable chances on Unfair mode too.
