This is a SRPG which you use mechas in turn-based combats. It was the new "Front Mission" game for mobile, but it had to change names, while it still holds almost the same gameplay
I'm enjoying it, but I went into this with the full comprehension of what a gacha is and that we exist in a system of capitalism.
You have to use VPN to bypass their connection issues and that is their official response, forums/reddit/discord is filled with connection issue complaint but they dont seem to care, they just tell you to use VPN or change connection.
You can sit there and try 50+ times and get in once, they have no clue whats wrong, probably using same host services...
To skip the long-winded and possibly contradictory detailing, if you're just looking for recommendation, I won't recommend it. You can accomplish everything gameplay-wise as a F2P, but it gets old rather quickly despite the draw of a modern turn-based tactical mecha, and that's not even considering the sheer amount of time and effort it will take you...
if you started on mobile and wanted to link your account to steam you are SOL. Have to have started on steam which means i screwed myself since i already bound my email to mobile
It's a perfect game to play if you like Front Mission
