Alien Coins are the limited-time event currency in Mini War, and the quickest way to stack them is to mass-produce Alien Oil and feed it into the Alien Extractor. One high-output generator plus the right worker does most of the work for you.
Quick answer: Clear your plot of your current generator, place a Super Drill (Super Oil Drill), assign a Super Worker to it for roughly +340 Alien Oil, equip the Alien General commander, then send the oil to the Alien Extractor to turn it into Alien Coins.
What you need before farming Alien Coins
The top setup relies on three things: a Super Drill, a Super Worker to staff it, and open space on your plot. If you are already running a high-tier generator like a Supernova, take it down first so the drill has room and your workers are free to reassign.
| Requirement | Why it matters |
|---|---|
| Super Drill (Super Oil Drill) | Highest Alien Oil output when staffed |
| Super Worker | Pushes the drill to roughly +340 Alien Oil |
| Alien General commander | Adds production speed and income buffs |
| Alien Extractor access | Converts Alien Oil into Alien Coins |
Fastest Alien Coin farming method (Super Drill)
Backup method if you don’t have a Super Drill
No Super Drill yet? A Black Hole works as a stand-in. It produces around 60 Alien Oil without needing Super Workers, so it is a much smaller haul but still keeps coins trickling in while you chase the better generator.
| Generator | Approx. Alien Oil | Needs Super Worker |
|---|---|---|
| Super Drill | ~340 | Yes |
| Black Hole | ~60 | No |
How to know it worked
When you run the conversion at the Alien Extractor, the interface reads “Alien crops → Alien coins!” and shows the amount being extracted, such as a +340 pop for a fully loaded Super Drill run. Your Alien Coin balance climbs immediately, and you can spend it on event items in the Alien Shop.
Where to get the Super Oil Drill
The Super Oil Drill comes from the Veteran Crate, and it carries a 5% drop rate. That low chance is why keeping a Black Hole running is worth it as a fallback until the drill finally lands.
Once the drill, the Super Worker, and the Alien General are all in place, the loop is simple: generate Alien Oil, convert at the Extractor, and repeat. That steady cycle is the fastest route to a full Alien Coin stockpile before the event window closes.
