The fastest Alien Coins route is a Super Oil Drill paired with a Super Worker, boosted by the Alien General, then run through the Alien Extractor to bank the coins — with the Black Hole as a weaker backup if you don’t have the drill yet.
The fastest Alien Coins farm is the dedicated oil setup: Super Oil Drill, Super Worker, Alien General, then cash out through the Alien Extractor. The Alien Invasion event made Alien Coins the currency everyone needs, and your speed comes down to running the right production machine instead of filling your base with general-purpose factories. Build around Alien Oil and the coins come in several times quicker. Here’s the exact build to farm them as fast as possible right now.

Best Alien Coin setup at a glance
| Part | Best use | Known number |
|---|---|---|
| Super Oil Drill | Main Alien Oil generator | Best output in the game right now |
| Super Worker | Amplifies the drill’s output | Pairs with the drill |
| Alien General | Passive production and resource boost | Optional multiplier |
| Alien Extractor | Converts resources into Alien Coins | Bank your coins here |
| Black Hole | Backup generator, no drill needed | Pre-drill stopgap |
The Alien General adds a passive multiplier on top, speeding up production and improving your overall resource gain. The Alien Extractor is where you turn the farmed resources into coins. If you don’t have the drill yet, the Black Hole is a much weaker stand-in.

Getting the Super Oil Drill from the Veteran Crate
The Super Oil Drill only comes from the Veteran Crate, and it is not a guaranteed pull. It drops at around a 5% chance, so expect to open a stack of crates before you get it. Drop rates vary, so treat this as a repeat-farm route. Put your crate openings into Veteran Crates instead of spreading them across other pulls, because this drill is the upgrade that turns the whole event farm from slow income into fast Alien Coins.
Keep opening the Veteran Crate while your Black Hole quietly farms in the background — you earn coins the whole time instead of idling, and the day the Super Oil Drill drops you switch straight into the fast setup.
Black Hole fallback before you own the drill
| Setup | Output | When to use |
|---|---|---|
| Super Oil Drill + Super Worker | ~340 Alien Oil | Your main farm once you own the drill |
| Black Hole, no workers | ~60 Alien Oil | Stopgap while grinding toward the drill |
If you don’t have the Super Oil Drill yet, run the Black Hole immediately. It generates Alien Oil by itself without needing a Super Worker, so it keeps your event income moving while you grind Veteran Crates.
Use it as a holdover, not the fast route. Every coin it brings in is progress toward the machine that replaces it.
Spending Alien Coins at the Alien Shop
Once the coins are rolling in, spend them at the Alien Shop. It stocks event-exclusive cosmetics, and the prices are low enough that a solid farming session covers several. The Alien Tree costs 8 Alien Coins, and the Alien Garrison costs 16 Alien Coins plus 50 Gems. Bank a buffer before the event ends, because these Alien Invasion items leave with the event.
Other Alien Invasion event methods and the Cores naming question
Farming oil with the drill is the fastest hands-on method, but the Alien Invasion event also pays currency through other activities. Run mutated crops through the Alien Extractor for a steady trickle, capture an Alien Base Outpost for periodic payouts while you hold it, and lock down the Alien King of the Hill base for the biggest single hits — around 100 to 1,000 at a time — when your team can keep control. Those are map-control plays, so they lean on PvP rather than a solo build.
The balance on your farm is labeled Alien Coins, while some Alien Invasion rewards use the name Alien Cores. For this route, Alien Coins refers to the farm balance you earn from oil and spend in the Alien Shop; Alien Cores refers to the event’s map-control reward wording.

Frequently Asked Questions
Can you farm Alien Coins without the Super Oil Drill?
Yes. The Black Hole generates Alien Oil without any Super Worker attached, so it works from the moment the event starts and before your crate luck comes through. Keep it running in the background while you open Veteran Crates, then swap it out the instant the drill drops — it’s a bridge, not a destination.
Is the Alien General required for this method?
No. It’s a boost, not a requirement. The Super Oil Drill and Super Worker do the heavy lifting on their own, and the Alien General adds passive speed and resource bonuses on top. Equip it if you have one, but start farming even without it.
Are Alien Coins and Alien Cores the same thing?
Alien Coins are the on-screen farm balance used in this loop — the setup shown sits at over 1.7 billion of them. Alien Cores is the event wording used for map-control rewards. Use Alien Coins for the oil-farm and Alien Shop route, and read Alien Cores as the map-control reward label.
