在殭屍末日過後，世界陷入長久的黑暗之中。城市失去生機，電網全面崩潰，而你作為最後倖存的維修員，肩負起恢復電力的重責大任，為人類僅存的安全區域帶回希望。

這是融合動作與解謎元素的遊戲，整體玩法圍繞在修復電網系統展開。在各個關卡中啟動所有發電機，才能順利前進。然而，看似簡單的操作背後，其實隱藏著高度策略性。電網系統極為不穩定，每當你切換一個開關時，周圍的裝置也會同步受到影響，產生連鎖反應。有些區域會因此重新點亮，但也可能讓原本已恢復供電的地方再次陷入黑暗。

隨著關卡推進，電網結構會變得越來越複雜，玩家必須仔細觀察整體布局，預測每一次操作所帶來的變化，並在有限的條件下找出最佳解法。每成功修復一台發電機，不只是完成關卡的一部分，更像是在這片荒蕪世界中點燃一絲希望。

遊戲共設計 50 個關卡，難度循序漸進，從基礎機制逐步發展到更具挑戰性的配置。玩家可使用扳手來啟動或關閉發電機，透過不斷嘗試與調整策略來克服難題。遊戲也提供無限次重試的機制，能夠在反覆實驗中掌握電網的運作規律，最終成功讓整個系統恢復運作，為世界重新帶來光明。

In the aftermath of a zombie apocalypse, the world has fallen into darkness. Cities lie silent, the power grid is shattered, and you are the last surviving technician. Your mission is to restore electricity and bring hope back to humanity’s final safe zones.

Gridz Keeper is an action puzzle game centered around repairing a broken power network. In each stage, players must reactivate all generators to progress. While the core mechanics are easy to understand, the gameplay quickly reveals its strategic depth. The electrical system is highly unstable—whenever you toggle a switch, nearby switches are also affected, triggering chain reactions. Some areas may light up again, while others fall back into darkness.

As you advance, the grid layouts become increasingly complex, requiring careful observation and planning. Players must anticipate the consequences of every action and find the most efficient sequence to restore power. Each repaired generator represents not just progress, but a small spark of hope in a devastated world.

The game features 50 progressively challenging levels. Using a wrench to activate or deactivate generators, players must experiment, adapt, and refine their strategies. With unlimited retries available, you’re free to learn from mistakes and gradually master the system, ultimately bringing light back to the entire grid.
