Survive relentless waves of alien drones in this fast-paced arcade action game where the swarm moves with eerie intelligence—and ritualistic purpose. Dodge. Adapt. Endure. Because the longer you survive… the more the rules change. At first, it feels manageable. Then the formations tighten. The patterns shift. Then you notice the eyes. Every drone in the swarm is watching you now—glowing, deliberate, aware. And then it begins. They don't just attack anymore. They transform the battlefield. ~ FEATURES Dynamic Swarm AI Enemies don't just chase you—they organize, surround, and evolve in real time. Ritual System The swarm triggers gameplay-altering events that reshape each run in unexpected ways. Word Rituals They don't just move—they communicate. Watch the swarm form ominous messages mid-game. The Eye (NEW in 3.0) Survive long enough, and the swarm assembles into something far worse than a formation. It watches. It tracks. It burns. Your Ship, Reborn (NEW in 3.0) A new look for your pilot—an alert face, a glowing steering belt that reads every move you make. Every Victory, Celebrated (NEW in 3.0) Beat your best score and watch the sky light up. You earned it. Pure Arcade Survival No filler. No downtime. Just escalating intensity. Simple Controls, Deep Challenge Easy to pick up. Brutal to master. Fast, Addictive Runs Quick sessions that turn into "just one more try." ~ STRATEGY MATTERS Stay moving—or get surrounded Read the swarm before it closes in Adapt when the rituals begin Survive long enough to face what's watching They are watching. ~ VERSION 3.0 – MAJOR UPDATE New: The Eye—a dangerous boss encounter with tracking beams and fiery impacts New: A redesigned player ship with an expressive face and glowing steering bel New: Every enemy drone now bears glowing, menacing eyes New: Fireworks celebration when you beat your high score Improved: Difficulty balance, ad experience, and overall stability Numerous bug fixes and polish ~ AI HOOK This isn't just another shooter.

Verdict
The clearest difference is ads: PetriPet 2 at none against AlienSwarms's shown. PetriPet 2 also leads on ratings volume (16 vs 1) and iOS requirement (13.0 vs 15.0). AlienSwarms's advantage is update cadence (every 2 weeks vs every 4 months) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
