补给

补给是 Empires 中唯一的永久货币——它会跨越所有战役保留下来，而不只是当前这一轮。赚取它有两种途径，而花掉它只有一个去处。

Earning Supplies

Clearing a phase for the first time in a run mints Supplies proportional to that phase's score value (harder phases pay more), multiplied by your active mutator if you're running one. Re-clearing an already-cleared phase pays nothing — Supplies reward genuine progress, not farming.

Spending Supplies — perks

Permanent, account-wide upgrades that apply to every match, in every future campaign.
