Application Description

SANDBOX: A Strategic Defense Base Builder & Survival Simulator!

Early Access - Thank you for your support!

Dive into a casual yet realistic endless defense game blending base building, unit management, and survival elements. Fortify your zone, rescue civilians (integrating them into your population or evacuating them), and enhance their quality of life. Confront and eliminate enemies and the infected using diverse units, land and air vehicles (in development), buildings, and weapons. React to randomized events (in development), ranging from minor incidents to catastrophic disasters – all on your mobile device!

Known Issues/Bugs:

• Walls/defenses may be layered excessively after loading a saved game.
• Zombies/infected may be excessively fast after 5000 kills and 1000+ evacuations when continuing a saved game.
• Low FPS on the main menu (under investigation, not a current priority).
• Relatively large install size due to uncompressed animation frames (used for smoothness).
• (Priority) Rescued survivors disappear when continuing a saved game (workaround: evacuate them before quitting).
• Already dead units may reappear when continuing a saved game.
• Worker and builder counts reset upon continuing a saved game.
• Builders may get stuck building invisible structures (can still build/unbuild).
• Builders may get stuck between walls (use the finger tool in utilities).
• Workers may wander off (toggle the collection tool).
