Upgrade Priority Tier List
A useful tier list should help you decide. This one ranks decisions using systems confirmed by the creator, not a fabricated drone roster.
BETA 8 changes quickly. Recheck your mining cycle after each group of upgrades—the bottleneck can move.
Your current bottleneck
Upgrade the part of the mining cycle that consumes the most time: breaking, carrying, or travel. This creates the clearest immediate gain.
Planet evolution progress
Preserve a path toward the next evolution, because larger worlds and rarer ore are creator-confirmed progression benefits.
Balanced support stats
Bring the other two fleet stats up once the primary bottleneck moves. Throughput depends on the whole cycle.
Luck and long roll sessions
Luck matters for rarer drones, but the public game description does not expose its full formula. Use visible in-game feedback and avoid invented breakpoints.
Tier list FAQ
What is the best upgrade in Mine a Planet?
There is no universal choice. Mining power, cargo, and speed solve different bottlenecks, so the best purchase is the one that shortens the slowest part of your current cycle.
Where is the drone rarity tier list?
A complete named drone roster and stable stat table are not published in the official source used here, so this page does not invent rankings.
