01Core mechanic
Expand across world maps, balance troop growth and choose the right moment to attack neighboring territories.
02How a run ends
Spending every resource immediately leaves the formation unable to answer a faster unit, new lane or stronger wave.
03Opening plan
Inspect lanes, costs and unit roles first; build one dependable defense and keep a small reserve for the first surprise.
04Common mistake
Avoid upgrading everything equally. Invest in the position or production step that is limiting the whole plan.
05Advanced tip
Expand cheaply into neutral space first, keep reserves on exposed borders and attack a rival only when the resulting frontier remains defensible.
