Till you Last: Safe Zone

Endless Defense Base Building Simulator: A strategic sandbox for unit survival and base management!

EARLY ACCESS

Thank you for your support!

Experience a casual yet realistic sandbox simulator blending endless defense, base building, unit management, and survival. Grow your safe zone into a formidable fortress. Rescue civilians to expand your population or evacuate them to ensure their safety. Enhance your people's quality of life, and eradicate threats—both infected and hostile forces—with diverse tactics. Command a wide array of units, air and land vehicles (WIP), buildings, and weapons. Handle randomized events (WIP), from minor incidents to catastrophic disasters, all from the power of your mobile device!

Known Issues/Bugs:

- Walls/Defenses become doubled/tripled layered after loading a saved game (Making your walls ultra-sturdy, just as a future president might want)

- Zombies/Infected become super fast at 5000+ kills or 1000+ evacuees when continuing a saved game

- Low FPS on the Main Menu (under investigation, but not a top priority at the moment–apologies)

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

- (Priority) Rescued survivors in holding disappear when continuing a saved game. This will be fixed in the next update. For now, evacuate them via chopper before quitting/exiting the game.

- Occasionally, 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 building something invisible (they can still execute the latest build/unbuild commands).

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

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