Missiles are the attack side of the cash loop
The official game description confirms that players arm themselves with missiles and destroy other players' buildings for cash and rewards. That means missile upgrades matter most when they improve the next attack cycle, not when a public page claims an unsupported exact rank.
Use role priorities until stats are verified
Exact missile names, damage, cost, range, speed, effects, and unlock paths are still open data gaps. The safe launch approach is to compare missiles by use case: early cash pressure, stronger building damage, risky target attempts, and recovery after failed attacks.
Upgrade missiles when attacks are the bottleneck
If your city is stable but attacks feel slow, route the next cash spend toward missile progress. If your buildings keep falling or cash runs dry, pause missile spending and use city upgrades, cash farming, or defense guidance first.
