SANDBOX Simple Strategy: An endless defense and base-building survival simulator where you command units!

EARLY ACCESS

Thank you for your support!

Dive into a casual, realistic sandbox simulator blending endless defense, base building, unit management, and survival. Grow your zone into a secure fortress, rescue civilians to boost your population or evacuate them to safety. Enhance your people's quality of life, and eliminate all threats—infected and foes alike—using diverse tactics, strategies, units, air/land vehicles (WIP), buildings, and weapons. Handle randomized events (WIP) from minor incidents to full-scale disasters, all from the power of your mobile device!

Experience true SANDBOX gameplay at your fingertips!

Inspired by survival colony, RTS, and sandbox simulation games on PC, with core survival elements adapted for mobile.

Known Issues/Bugs:

- Walls/defenses become double or triple-layered after loading a saved game (making them ultra-sturdy, just as a future president might want)

- Zombies/infected become extremely fast after 5000 kills or 1000+ evacuations when continuing a saved game

- Low FPS on the main menu (under investigation, but not a current priority—apologies)

- Fairly large install size due to How-To-Play animations (uncompressed GIF frames were used for smooth, clear visuals)

- (Priority) Rescued survivors in holding disappear when continuing a saved game. Fix coming next update; workaround: evacuate them via chopper before quitting.

- Occasionally, single units already dead appear alive when continuing a saved game

- Worker and builder counts reset to 4/5 when continuing a saved game

- Sometimes builders get stuck constructing something invisible (they can still execute latest build/unbuild commands)

- Sometimes builders get stuck between built walls; use the finger tool in utilities to interact with units

- Workers may wander off occasionally; toggle the collection tool to redirect them to work.
