Fast answer
The answer before the background
Alien Shooter TD Coins are an official mobile resource: Sigma Team says daily supply crates can contain ammunition, weapons, Coins and ammo. The stores also describe Money returned by dismantling weapons, auxiliary supplies, limited ammunition and paid Minerals on iOS. These are not interchangeable. Repeat a mission the current team can clear without excessive ammo or consumable cost, collect the daily crate, dismantle only verified duplicates and spend Minerals only after reading the live offer. Steam is a paid edition and its economy must be checked in that build rather than copied from mobile.
Resource map
Use the official names
| Resource | Verified role | Farming rule |
|---|---|---|
| Coins | Included in official mobile daily supply crates | Claim the supported crate and record the actual amount/version. |
| Money | Returned when a weapon is dismantled | Salvage only a duplicate or item with no planned class role. |
| Minerals | Named Apple in-app-purchase item | Treat as premium; prices and offers are region-sensitive. |
| Ammunition | Limited per weapon and replenished in combat | Subtract refill and supply cost from a mission's value. |
| Auxiliary supplies | Can come from weapon disassembly | Track the exact material and intended modification. |
| Gems / diamonds / crystals | Not the exact first-party English labels used in the checked stores | Map translated search terms to Coins, Money or Minerals only after checking the icon. |
Repeatable loop
Measure profit after ammunition
Choose a mission where the same placements and weapon set clear reliably. Record Coins, Money, weapons, supplies, ammunition used, drones, bombs, mines and time. A harder stage is not a better farm if refill or consumable cost erases the payout.
Run three times, then decide whether the bottleneck is deployment cash, ammo, a keeper weapon, modification material or Minerals. The answer changes the next action. Farming Coins does not solve a class-compatibility problem, and buying Minerals does not fix poor placement.
Spending
Preserve a deployable platoon
- Keep one affordable, reliable weapon for each soldier role used on low-budget missions.
- Do not upgrade every weapon if stronger gear raises deployment or ammo cost beyond the mission start.
- Use supply drones where they refill several active soldiers at the critical time.
- Save premium Minerals until the current store shows the exact item, odds or guaranteed result.
Platform audit
Do not merge mobile and Steam results
Label Android package, Apple app ID or Steam app, plus version and region. The mobile descriptions explicitly say free with ads/IAP and daily crates, while Steam sells the native Windows game. A payout or IAP table from one storefront is not proof for another.
For every guide result, preserve the exact English resource label beside its icon. This prevents Minerals from becoming fictional diamonds, and prevents in-mission ammunition from being counted as permanent currency. The generator page handles unlimited claims safely.
