SANDBOX: An Endless Defense, Base Building, and Unit Survival Simulator with a Simple Strategy Core!

EARLY ACCESS

Thank You for Your Support!

Dive into a casual, realistic sandbox simulator blending endless defense, base building, unit management, and survival. Transform your zone into a secure fortress. Rescue civilians to grow your population or evacuate them to safety. Enhance your people's quality of life, and use diverse tactics with a wide array of units, air and land vehicles (WIP), buildings, and weapons to cleanse the land of foes and the infected. Handle randomized events (WIP), from minor incidents to catastrophic disasters—all from the power of your mobile phone!

Known Issues/Bugs:

- Walls/Defenses become doubled/tripled layered after loading a saved game (resulting in ultra-sturdy walls, "just as a future president might desire").

- Zombies/Infected become extremely fast after 5000 kills or 1000+ evacuees 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 used for smooth, clear visuals).

- (Priority) Rescued survivors in holding disappear when continuing a saved game. Will be fixed next update. Current workaround: Evacuate them via chopper before quitting.

- Occasionally, single units that were killed are alive upon continuing a saved game.

- Worker and Builder counts reset to 4/5 upon continuing a saved game.

- Sometimes builders get stuck constructing something invisible (they remain responsive to the latest build/unbuild commands).

- Sometimes builders get stuck between built walls. Use the finger tool in the utilities menu to interact with them.

- Workers may wander off occasionally. Toggle the collection tool to direct them back to work.
