HoldoutSupport
How to play
Zombies follow the road toward your base. Pick up to six tower cards before a match, build towers beside the road, upgrade them with the scrap you earn, and survive all 35 waves to win the battlefield. Every match earns credits and research points: spend credits in Supply on crates and new towers, and research points in Tech on each tower’s upgrade tree. A tutorial runs in your first match; replay it any time from Settings → Tutorial.
Frequently asked questions
Do I need an internet connection?
No. Holdout is fully offline and single-player.
Where is my progress saved? Can I move it to a new phone?
Progress is saved on your device only. There is no account or cloud save yet, so deleting the app deletes your progress. Your device backup or a device-to-device transfer may carry the app data over, but we cannot guarantee it.
How do I start over?
Settings → Reset progress, then tap again to confirm. This cannot be undone.
How do I change the language?
Settings → Language: English or 中文 (Simplified Chinese).
Does the game have ads or in-app purchases?
No. Crates and towers are bought only with credits earned by playing.
The game runs slowly or gets hot.
Set Settings → Graphics to Medium or Low, and close other apps.

玩法
僵尸会沿着道路冲向你的基地。开局前最多选择 6 张防御塔卡牌，在道路两侧建造防御塔，用击杀获得的资金升级它们，守住全部 35 波即可拿下该战区。每局结束都会获得军饷和科技点：军饷在「补给」中购买补给箱和新防御塔，科技点在「科技」中研发每座塔的强化。首局会有新手教学，可随时在「设置 → 新手教学」中重新开启。
常见问题
需要联网吗？
不需要。《死守》是完全离线的单机游戏。
进度保存在哪里？换手机能带走吗？
进度只保存在本机，目前没有账号和云存档，删除 App 会同时删除进度。设备备份或换机迁移可能会带上 App 数据，但我们无法保证。
怎样重新开始？
「设置 → 重置进度」，再点一次确认。此操作无法撤销。
怎样切换语言？
「设置 → 语言」：中文或 English。
有广告或内购吗？
没有。补给箱和防御塔只能用游戏中获得的军饷购买。
游戏卡顿或发热？
把「设置 → 画质」调到中或低，并关闭其他 App。
