@@b.n3718 i don’t play ASW very often on mobile. I use the simulator to only see what happen in the newest seasonal map. You can join the official discord to look for more active players.
It is on pc, use the mobile game simulator called AS-Gold. Sigma once leak it by accident. I played it by replacing it with the normal campaign level, so the lid file is incomplete. I have no idea on how to fix it.
For the mobile version, you will get several supply box after defeat the boss, and for season one, hold on after several minute. And on pc, the reward means nothing, you can directly buy power unit from store without paying anything.
