## What is 回线：BACKTRACE?

子弹不会在去程造成伤害。真正的攻击，发生在它沿原轨迹归来时。

BACKTRACE / 回线是一款围绕“返程弹道”构筑的俯视角动作 roguelite。你只有六枚不会消耗的弹丸：把它们射向墙面，利用反弹布置未来的杀伤线；引诱敌人进入轨迹；在正确时机召回；最后赶回旧射击点，接住归来的弹丸并维持战斗节奏。

核心特色：

- 独特的返程伤害机制：去程布线，返程穿透敌群；
- 六枚永久弹丸：每次发射都同时创造弹道与必须返回的锚点；
- 主动召回、相位冲刺、反弹、标记和接弹组成高密度战术循环；
- 五波完整单局、四类敌人和多阶段 Boss“收债人”；
- 九项围绕返程、反弹和接弹设计的局内升级；
- 为 iPhone 与 iPad 横屏设计的双虚拟摇杆和快捷按钮；
- 离线单机、无广告、无应用内购买；
- 降低闪光、关闭震动、瞄准辅助和色觉符号等辅助选项。

先决定子弹将如何回来，再决定自己要去哪里。
