Buy Swarm Queen Cheaper!

You're an insectoid alien fighting over Jupiter’s moon Europa.

It’ll be a tough battle - a test of your strategy, intuition, and perseverance.

Your minions control themselves, using "fuzzy logic" to pick the best target.

Your job as the queen is to focus on strategy.

Mutate your eggs so you can create combat minions - but you only have 4 "egg slots", so you must choose.

Make sure to spawn Harvester bugs to collect nectar resources.

When and what you choose to spawn or mutate is a big part of the tactical choice.

And always watch the chaos of battle. Predicting the outcome of a fight can help you decide your next move.

In each of the 21 campaign levels, the enemy Swarm Queen has a new unit or ability, which you then unlock for use in later levels.
                                          
The enemy queen spawns Harvesters, collects nectar, and unlocks units just like you do. She judges the situation and tries to counter you as best as she can.

The enemy’s advantage is that she has a surprise new unit or ability in each level. But, she usually only has access to a few other units. (You can view the enemy’s unit list before starting the level or in the “pause” screen in-game.)

Completing the campaign unlocks some “challenge levels”, which put a twist on normal gameplay.

You could also try going back and beating levels on hard mode (good luck!), or starting a “New Game Plus” (added in a free update) with extra nectar for both queens.

In the biggest update yet, version 2.0 includes an alternate "cartoon" art style, Steam achievements, visible enemy "emotions", an "easy" difficulty setting, and more!

Swarm Queen is inspired by insects, and classic sci-fi aliens like Xenomorphs, Zerg, and the "Bugs" from Starship Troopers. It's like a war between ant colonies, but in space!
