Synchronize iOS and Android versions

The iOS version has not been updated since 2019, leading to high-frequency user complaints and missed revenue from the iOS ecosystem.

Implement Modern Meta-Progression

Competitors like Tank Stars and GunboundM use chest-based and avatar systems to drive long-term engagement, a clear feature gap for Annelids.

Feature Gaps vs Competitors

  • Chest-based weapon progression (available in Tank Stars)
  • Avatar/Mobile-suit RPG stats (available in GunboundM)
  • 3v3 Isometric real-time combat (available in Tanks a Lot)

Key Takeaways

Annelids is an 'underrated masterpiece' with a unique mechanical hook in destructible terrain, but it is currently coasting on nostalgia. To survive against high-polish rivals like Tank Stars, the developer must bridge the massive iOS update gap and stabilize multiplayer infrastructure.

Where Is It Heading?

Stable

Android version updated in April 2026 — indicates active maintenance of the largest user base.

iOS version stagnant since 2019 — signals platform abandonment and high churn risk for Apple users.

Sentiment remains 'Excited' due to nostalgia, but update anxiety is a growing theme in recent reviews.

FAQ

Is Annelids good for phones with low storage?
Yes. One of Annelids' primary strengths is its small 18MB footprint, making it ideal for older devices or users with limited storage space while still offering 68 missions and multiple game modes.
How does Annelids compare to Tank Stars?
While Tank Stars focuses on surface-level 1v1 artillery duels with high-fidelity graphics, Annelids features 360-degree underground tunneling and fully destructible environments, offering more tactical 'hiding' and digging mechanics.
Is Annelids still being updated in 2026?
The Android version is actively maintained with updates as recently as April 2026. However, the iOS version has not received an update since December 2019, leading to potential compatibility issues on newer iPhones.
What is a good alternative with more RPG elements?
If you enjoy artillery combat but want deeper progression, GunboundM is a strong alternative. It features an 'Avatar' and mobile-suit system with unique stats and RPG-lite strategy that Annelids lacks.
