i have done 4 10 summons between maintenence periods and have gotten 7 SR characters so far.
auto play was available very quickly, compared to other games. some mechs dont come with weapons, apparently. tried to equip some, and i couldn't start the mission stage because the party members didnt have guns. not sure if i get "armed" mecha later on, because of the frequent maintenance periods right now.
tutorial seemed very concise and not drawn out, which i appreciate. but there might be more, since I've only completed stages 1-1 and 1-2 with my limited time playing.
there also wasnt a progress bar on the loading and in game download screens. that i could see. [shrugs in confusion]
