About this game

💥 THE ULTIMATE SURVIVAL TOWER DEFENSE GAME 💥
Join the relentless fight in Tower Survival: Hammerstorm! A massive horde of slime enemies is attacking your lone tower, and your only goal is to survive the endless waves. This isn't just a strategy game—it's a test of wit, resource management, and pure defensive power.

The battle takes place in intense sessions that last until your tower falls. You must use your automated hammers to destroy the slimes and collect wood. This wood is your lifeline, allowing you to quickly buy powerful, temporary upgrades to stay ahead of the onslaught.

📈 PERMANENT RPG PROGRESSION & DEEP UPGRADES
What makes Hammerstorm truly addictive is the long-term RPG progression. Every session contributes to your permanent power!

Permanent Upgrades with Emeralds: Slimes occasionally drop rare Emeralds. Spend this currency between sessions to unlock lasting improvements for your tower. Invest in permanent Damage, Attack Speed, Max HP, Regeneration and other vital stats so you start every run stronger than the last.

Talents and Skills System: Go beyond base stats! Use Slime Essence and Slime Crystals to acquire powerful Talents (passive global buffs) and active and passive Skills (like freezing enemies or calling down a barrage of meteors). Strategically building your loadout is key to mastering the higher-difficulty survival waves.

🔥 TACTICAL UPGRADE CATEGORIES
Victory hinges on smart resource allocation during a run. Use your wood to invest in three core categories:

OFFENSE: Boost your tower's primary weapon with upgrades to Damage, Attack Speed, Critical Damage, and hammer Quantity. Destroy the slime armies before they reach your walls!

DEFENSE: Ensure your tower survival with enhancements to Max Hp, Hp Regen, and Damage Reduction. Use emergency Repair to pull yourself back from the brink of defeat.

UTILITY: Maximize your economy. Upgrade your Wood Capacity and Wood Rate by improving the Saw Mill to generate crucial passive income, giving you the resources for faster, more powerful upgrades.

If you enjoy deep progression, rewarding grind, and high-intensity strategy action, your next favorite mobile game is here. Can you outlast the hordes and become the ultimate defender in Tower Survival: Hammerstorm?

Very good game, passes time well, and the developer is a great guy, listens to community feedback, and implements good feature ideas into the game. It isn't riddled with ads, but there are a few. This is one of the only games or apps where I don't mind watching the ads to support the game since it does genuinely deserve it. Great game, definitely recommend.

Hello there! Sorry for the inconvenience. The freeze issue has hopefully been fixed. If you still encounter it, please let me know if possible!

If there were additional upgrades and an endless mode I would rate it higher. The skill tree is pretty boring with repeating stat increases with a few outliers. Examples of fun things that could be implemented: Lifesteal, chaining, piercing, aoe size, splitting projectiles. Auras, slow aura, dmg aura and so on. Defensive stats such as an energy shield that regenerates and so on. endless mode pls add 🚀

An endless mode is a nice idea. I also like the suggestions for new buffs! I have a couple of other game modes on the way that might make things more interesting as well. Thank you dor your feedback!
