That's interesting . . .
It should save your progress in your browser.
Finally got back to the game and finished it a couple of times. To bad that after finishing campaign you basically have only 4 maps to play.
Also I feel bad for Alicia. F tier comander. You have no use of better healing if your units are weak and can't even survive the fight.
Anyway, I really like how game balance works and simple tanks can't really fight infantry so recon is always a thing.
