Hi all,
not sure if anyone reported this (couldnt find such message), but there is a glitch in aeon coop mission 3 (it is a version of old glitch i ve seen in original supcom campaign on that exact mission):
if you capture UEF tech there you get access to ALL UEF T2 tech (including T2arty, TML, TMD, almost all T2 units (except cruisers, hovertanks) etc). What is different from vanilla coop is that now you also get almost all FA/FAF T2 units/buildings (engineering stations and even new T2 factories). By campaign you are not really supposed to have that stuff (though using coopers, januses, mongooses and so on is entertaining in vanilla campaign).
From what I understand that was a very mission-specific glitch that now carried over to coop version (probably the code that defines units allowed/prohibited for that mission is wrong on UEF part).
