About this game

Giant Defense: Battle for Survival

In a distant past, when giants suddenly emerged and ruthlessly invaded cities, humanity faced an unprecedented threat. To survive, humans were forced to sail far and wide, seeking remote islands where they hastily constructed fortresses to protect themselves from these colossal creatures.

For a time, these giants found themselves unable to assault these isolated islands, allowing humans to survive. However, a mysterious change has occurred. Giants now tread upon the once-protected shores, launching ferocious attacks on the carefully built castles and settlements of humanity.

As humans fight for survival, you must confront the giants. Embark on a heroic journey in "Giant Defense" to defend your homeland and loved ones. Customize your defenses, manage your resources, and engage in epic battles against these colossal beings.

Key Features:

  • Formidable Enemy Lineup: Face challenges from over 10 powerful adversaries, each with unique strengths and weaknesses.
  • Multi-Lane Warfare: Defend against attacks from up to 4 massive creatures simultaneously; at critical moments, you must strategically choose your battle positions.
  • Immersive 3D World: Navigate freely on fully 3D maps with adjustable viewing angles that immerse you in the battles.
  • Easy Controls: Master the game with easy-to-use controls and automatic game saving, allowing you to enjoy the gameplay.
  • Tower Upgrades: Command 8 different types of upgradable towers, each with unique special abilities to strengthen your defense.

    Update Notes For Feb.25

    In the past few days, I've spent a significant amount of time further fixing some bugs in the game, including those related to pathfinding, interface switching, and scene details. The specific improvements are as follows: (1) Fixed some game bugs that affected the player experience. For example, some turrets on high ground couldn't attack properly when monsters couldn't reach them. (2) Finally, I added the captain character that I've always wanted to include. She/He will tell you the mission for each step. (3) Added four new maps for Sophia Island. Except for the special maps that require multiple challenges, you can enjoy more battle maps in the early stage of the game.

    Update Notes 2025.2.21

    In this version, I've fixed the bug related to level selection. Additionally, the latest progress of the story mode has been added, allowing you to directly resume your best progress from the menu. Moreover, I've introduced a long - awaited commander character. She only appears when chatting with you. I hope you all like it! Furthermore, in this update, you can now know your difficulty level during battles. Of course, if you want to change the difficulty, you'll still need to go to the settings menu, as it's not possible to modify the difficulty during combat.
