Ant Legion Codes: Active and Expired (June 2026)
Last checked May 28, 2026 (UTC)
Ant Legion codes are free Diamonds on a short fuse, most die within a couple of weeks of appearing, so the only list worth reading is a recent one. This is mine, and dead codes get cut the day I find them.
Ant Legion: For The Swarm codes are gift codes Star Union posts around updates, server milestones, and seasonal events, exchanged for free Diamonds, speedups, resources, and the odd evolution item. Strategy games run on compounding, and that's the lens for these rewards. Diamonds accelerate evolution, speedups collapse timers, resources keep the colony building, and all of it lands earlier in your power curve than anything you'd grind later. A mediocre reward claimed today beats a great one claimed next month.
Quick tip. put code Diamonds into colony evolution and unit upgrades, never cosmetics. Your swarm's power is the only stat the map respects, and a skin has never won anyone a fight.

Active Ant Legion: For The Swarm codes (4)
Redeem these now, not after your next session. I once saved a code for a quieter week, came back twelve days later, and got exactly the invalid message I deserved. Two weeks is a generous lifespan here.

- Open Ant Legion and tap into the settings menu.
- Find the gift code or redeem option.
- Paste the code exactly as written.
- Confirm, then open your mailbox and collect the Diamonds and resources.
Claim mailbox rewards promptly and spend them with a plan. Speedups and resources do their best work fed into your current evolution push, not sitting in storage looking comfortable.
Ant Legion: For The Swarm codes FAQ
What's in a typical code drop?
Diamonds, speedups, resources, occasionally an evolution or unit item. A standard strategy game care package, and all of it compounds if you spend it on power instead of polish.
Best use of code Diamonds?
Evolution and units. Power wins fights, fights win the map. Cosmetics are for players who've already won.
Why did my code fail?
Nine times out of ten it simply expired, because these die fast. Otherwise you've already claimed it or a character got mistyped, and the Copy button rules that last one out.
Where do I type codes in this game?
Settings menu, gift code option, then collect from your mailbox. Thirty seconds, start to finish.
Can you build a strong colony free to play?
Yes, with patience and a decent alliance. Codes, events, and dailies keep a steady trickle of Diamonds and resources coming, and a free player who funnels everything into evolution and units ages well here. The spenders sprint, you marathon.
Where are new Ant Legion codes announced?
Official social channels and in game event notices, usually packaged with the event details. Catch them early, because by the time a code has made the rounds online, part of its fuse is already burned.
