Absolute hot garbage, login fails constantly, cannot accept missions/rewards/mail, cannot watch ads for anything period, 9 times out of 10 tapping a button doesn't do anything whether it's upgrading a quest or buying a mech or just upgrading. Literally the worst mobile game I have ever played and that's not exaggerating. It's just a slimy, steamy pile of green poo clone of Endless frontier. Don't release an app that doesn't even work. C'mon.
