Fleet Upgrades Build

The alternating upgrade framework

Mid-game fleet building follows a rhythm: identify bottleneck, buy one meaningful tier in that stat, re-measure, repeat. Players who dump twenty levels into mining without checking cargo often hit walls that one cargo purchase would have prevented.

Think in rounds, not streaks. A typical healthy round: mining upgrade → cargo upgrade → speed upgrade → evaluate drone count → return to mining if evolution raised ore hardness. Adjust order when diagnosis says otherwise.

Round one: establishing baseline throughput

First objective: lasers clear starter ore at acceptable speed. Second: holds carry a full pull from the best deposit you farm. Third: one round-trip completes without painful transit gaps.

Do not unlock a third or fourth drone until round one feels smooth for your best ore. Extra drones multiply inefficiency if the fleet still trips on mining or cargo limits.

• Mining power until dig phase no longer dominates
• Cargo until holds fill on typical pulls
• Speed until transit is not the longest phase

Round two: scaling with drone count

Once baseline throughput exists, drone slots become efficient multipliers. Each new drone should increase hourly income noticeably. If not, fix fleet stats before buying another slot.

After adding drones, mining power often needs another bump — more lasers compete for deposits. Cargo follows because parallel hauls need larger holds to avoid partial trips. Speed last in the round unless transit visibly regressed.

Evolution checkpoints

Before evolving: save enough currency for at least one fleet upgrade in each stat after evolution completes. Evolution without follow-up upgrades causes post-spike crashes where ore is valuable but your fleet cannot mine it efficiently.

After evolving: run three timed cycles. Note which phase lengthened most — that stat gets first post-evolution spend. Ore value jumps make cargo upgrades especially attractive if holds were already filling pre-evolution.

Currency discipline

Keep a rolling reserve for reactive upgrades after surprise evolution costs or event expenses. Zero-balance spending feels fast until a new ore tier arrives and you cannot afford the mining catch-up.

Spend consumables during fleet upgrade sessions when you can stay online to verify improvements. A time skip before fixing bottlenecks accelerates the wrong loop.

Free drone rolls fit between rounds as variance — never skip a guaranteed fleet tier to save for rolls.

Example round walkthrough

Imagine three drones farming your best ore. Cycles feel fast, but income plateaued. You time one trip: mining finishes quickly, holds fill, yet transit and deposit waiting take most of the loop. That diagnosis makes speed the next purchase — not another mining tier.

After speed, income jumps. Next round, holds stop filling completely — cargo becomes the lead purchase. After cargo, mining needs a small bump because evolution is approaching and ore hardness will rise. That is a healthy mid-game round pattern.

Write your own diagnosis before copying this example. Your fleet counts, ore tier, and evolution timing differ — only the measure-first habit transfers universally.
