SANDBOX: A Strategic Defense Base Builder – Early Access

Thank you for your support!

Dive into this casual yet realistic endless defense game, combining base building, unit management, and survival elements. Build and fortify your zone, rescue civilians (integrating them into your population or evacuating them), and improve their quality of life. Employ diverse tactics and strategies using a wide range of units, air and land vehicles (WIP), buildings, and weapons to combat foes and the infected. React to randomized events (WIP), from minor incidents to catastrophic disasters—all on your mobile device!

• Low FPS on the main menu (under investigation).
• Large install size due to uncompressed animation frames.
• Rescued survivors may disappear when continuing a saved game (workaround: evacuate before quitting).
• Some units may reappear alive after loading a saved game.
• Worker and builder counts may reset.
• Builders may get stuck building invisible structures or between walls (use the finger tool in utilities).
• Workers may wander off (toggle the collection tool).
